TL;DR: In this paper, the effects of film strain and crystallographic orientation on the properties of Hf0.5Zr 0.5O2 films were examined using a (111)-textured Pt bottom electrode.
Abstract: To elucidate the origin of the formation of the ferroelectric phase in Hf0.5Zr0.5O2 films, the effects of film strain and crystallographic orientation on the properties were examined. Using a (111)-textured Pt bottom electrode, Hf0.5Zr0.5O2 films with a (111)-preferred texture inappropriate for transforming their phase from non-ferroelectric tetragonal to ferroelectric orthorhombic phase were deposited. In contrast, randomly oriented Hf0.5Zr0.5O2 films, grown on the TiN electrode, showed feasible ferroelectric properties due to their transformation to the ferroelectric orthorhombic phase. The origin of such transformation is the large in-plane tensile strain for the elongation of the c-axis of the tetragonal phase.

TL;DR: In this paper, the authors performed first-principles calculations with the nonlocal van der Waals (vdW) correlation to investigate the crystal structures and electronic and optical properties of CH3NH3PbI3.
Abstract: Methylammonium lead iodide perovskite, CH3NH3PbI3, has attracted particular attention because of its fast increase in efficiency as solid-state solar cells. We performed first-principles calculations with the nonlocal van der Waals (vdW) correlation to investigate the crystal structures and electronic and optical properties of CH3NH3PbI3. The calculated results show that the distribution of methylammonium ions, which further changes the vdW interaction and hydrogen bonds of organic and inorganic matrixes, plays a vital role in both the geometry stability and the electronic structure. The vdW correlation is critical to provide appropriate descriptions of the interaction between the organic and the inorganic parts. The phase transformation from orthorhombic to tetragonal phase causes the decrease of the band gap and the red shift of the optical absorption coefficient.

TL;DR: It is demonstrated that orthorhombic V2O5 can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon, and that a large portion of the sodium-ion storage, particularly at high current rates, is due to the V2 O5 pseudocapacitance.
Abstract: For the first time, we demonstrate that orthorhombic V2O5 can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V2O5 shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V2O5/C composite was fabricated by a novel ambient hydrolysis deposition that features sequential water vapor adsorption in nanoporous carbon, followed by a hydrolysis reaction, exclusively inside the nanopores. The unique structure of the nanocomposite significantly enhances the capacity as well as the rate performance of orthorhombic V2O5 where the composite retains a capacity of over 90 mAh/g at a current rate of 640 mA/g. Furthermore, by calculating, we also revealed that a large portion of the sodium-ion storage, particularly at high current rates, is due to the V2O5 pseudocapacitance.

TL;DR: The crystal structures are successfully established for tetragonal and orthorhombic CH3NH3PbX3 (X = I and Br) and the equilibrium lattice parameters are computed by the DFT+D2 method, and the results are compared to experimental values.
Abstract: The crystal structures are successfully established for tetragonal and orthorhombic CH3NH3PbX3 (X = I and Br). The equilibrium lattice parameters are computed by the DFT+D2 method, and the results are compared to experimental values. The band dispersions and electronic densities of states are calculated by HSE06, showing that their band gaps are in the range from 1.63 to 2.3 eV. Although the calculated dielectric functions of MAPbX3 compounds are similar to other semiconductors, the absorption spectra of their bulk crystals are drifted away from visible light spectrum. The effective mass tensors of holes and electrons are also evaluated in three principal directions at the Γ point. The anisotropies in the effective masses of the hole and electron are illustrated for two orthorhombic phases.

TL;DR: The origin of the ferroelectric polarization switching in orthorhombic HfO2 has been investigated by first principles calculations as mentioned in this paper, which can lead to a saturated polarization as high as 53μC/cm2.
Abstract: The origin of the ferroelectric polarization switching in orthorhombic HfO2 has been investigated by first principles calculations. The phenomenon can be regarded as being the coordinated displacement of four O ions in the orthorhombic unit cell, which can lead to a saturated polarization as high as 53 μC/cm2. We show the correlation between the computed polarization reversal barrier and the experimental coercive fields.

TL;DR: In this paper, the crystal structure of the high-temperature form of Na3V2(PO4)2F3 (at 400 K) was determined for the first time using very high angular resolution synchrotron radiation diffraction.
Abstract: Na3V2(PO4)2F3 is a material that has been attracting great interest as a potential positive electrode for Na-ion batteries. Its crystal structure was determined from single-crystal X-ray diffraction in 1999 by Le Meins et al. in the tetragonal space group P42/mnm at 298 K. In this work, we show how the use of very high angular resolution synchrotron radiation diffraction reveals a subtle orthorhombic distortion with unit-cell parameters of a = 9.02847(3) A, b = 9.04444(3) A, c = 10.74666(6) A in the Amam space group. Although this only slightly impacts the structural framework of the material, it reveals a significantly modified distribution of Na ions. Furthermore, the crystal structure of the high-temperature form of Na3V2(PO4)2F3 (at 400 K) was determined for the first time. This allowed comparing the totally disordered distribution of Na ions in this case with the partially ordered one of the room-temperature phase. We report here on an original structure and on an original electrochemical signature f...

TL;DR: In this article, a single crystalline orthorhombic phase tungsten trioxide monohydrate (O-WO3·H2O, space group: Pmnb) nanoplates with a clear morphology and uniform size distribution have been synthesized by the hydrothermal method and fabricated on the surface of fluorine doped tin oxide (FTO) coated glass substrates with selective exposure of the crystal facet by the finger rubbing method.
Abstract: Single crystalline orthorhombic phase tungsten trioxide monohydrate (O-WO3·H2O, space group: Pmnb) nanoplates with a clear morphology and uniform size distribution have been synthesized by the hydrothermal method and fabricated on the surface of fluorine doped tin oxide (FTO) coated glass substrates with selective exposure of the crystal facet by the finger rubbing method. The rubbing method can easily arrange the O-WO3·H2O nanoplates along the (020) facet on the FTO substrate. The O-WO3·H2O nanoplate can be converted to monoclinic phase WO3 (γ-WO3, space group: P21/n) with dominant crystal facet of (002) without destroying the plate structure. Crystal morphologies, structures, and components of the powders and films have been determined by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Raman, X-ray photoelectron spectroscopy, etc. The band gap energies of the O-WO3·H2O and γ-WO3 nanoplates were determined as ca. 2.26 and 2.49 eV, respectively. Photoelectrochemical prop...

TL;DR: In this paper, the synthesis and the gas sensing properties of novel mixed phase coexistence SnO2 nanorods are presented, which are obtained by calcinations of SnC2O4 synthesized with a chemical precipitation method using SnCl2·2H2O and PEG 400 as precursors.
Abstract: The synthesis and the gas sensing properties of novel mixed phase (i.e., tetragonal and orthorhombic phase) coexistence SnO2 nanorods are presented. The mixed phases SnO2 nanorods were obtained by calcinations of SnC2O4 synthesized with a chemical precipitation method using SnCl2·2H2O and PEG 400 as precursors. The resulting nanorods appear as polycrystalline composed of spherical mixed phases SnO2 nanocrystals and have a high surface area. It was observed that the calcination temperature was the key parameter determining the content of the orthorhombic phase. The as-synthesized compounds were used as sensing materials of the sensors of indirect heating structure and tested for their ability to detect volatile organic compounds (VOCs), such as isopropanol, acetone, alcohol, and formaldehyde. Gas sensing tests showed that these mixed phases SnO2 nanorods are highly promising for gas sensor applications, as the gas response for isopropanol was significantly enhanced by the presence of orthorhombic phase (S ...

TL;DR: It is demonstrated that interfacial structural coupling can play a critical role in the functional properties of oxide heterostructures.
Abstract: We investigate structural coupling of the MnO6 octahedra across a film/substrate interface and the resultant changes of the physical properties of ultrathin La2/3Sr1/3MnO3 (LSMO) films. In order to isolate the effect of interfacial MnO6 octahedral behavior from that of epitaxial strain, LSMO films are grown on substrates with different symmetry and similar lattice parameters. Ultrathin LSMO films show an increased magnetization and electrical conductivity on cubic (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT) compared to those grown on orthorhombic NdGaO3 (NGO) substrates, an effect that subsides as the thickness of the films is increased. This study demonstrates that interfacial structural coupling can play a critical role in the functional properties of oxide heterostructures.

TL;DR: The effect of Zr, Hf, and Sn in BaTiO3 has been investigated at close composition intervals in the dilute concentration limit in this paper, and the results show substantial enhancement in the longitudinal piezoelectric coefficient (d(33)).
Abstract: The effect of Zr, Hf, and Sn in BaTiO3 has been investigated at close composition intervals in the dilute concentration limit. Detailed structural analysis by x-ray and neutron powder diffraction revealed that merely 2mol. % of Zr, Sn, and Hf stabilizes a coexistence of orthorhombic (Amm2) and tetragonal (P4mm) phases at room temperature. As a consequence, all the three systems show substantial enhancement in the longitudinal piezoelectric coefficient (d(33)), with Sn modification exhibiting the highest value similar to 425 pC/N.

TL;DR: In this paper, the structure, optical and magnetic properties of LaFeO3 nanoparticles synthesized by the polymerized complex method were reported, which were successfully obtained from calcination of the precursor at different temperatures from 750 to 1,050°C in air for 2.h.
Abstract: This work reports the study the structure, optical and magnetic properties of LaFeO3 nanoparticles synthesized by the polymerized complex method. The LaFeO3 nanoparticles were successfully obtained from calcination of the precursor at different temperatures from 750 to 1,050 °C in air for 2 h. The calcined LaFeO3 nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–Visible spectroscopy, X-ray photoelectron spectroscopy (XPS), X-ray absorption near edge spectroscopy (XANES) and vibrating sample magnetometry. The XRD and TEM results showed that all LaFeO3 samples had a single phase nature with the orthorhombic structure. The estimated crystallite sizes were in the range of 44.5 ± 2.4–74.1 ± 4.9 nm. UV–Vis spectra showed strong UV and Vis absorption with small band gap energy. The valence states of Fe ions were in the Fe3+ and Fe4+ state, as confirmed by XPS and XANES results. The weak ferromagnetic behavior with specific saturation magnetization of 0.1 emu/g at 10 kOe was obtained for the small particle of 44.5 ± 2.4 nm. The uncompensated spins at the surface was proposed as playing a part in the magnetic properties of small sized LaFeO3.

TL;DR: The hard magnetic phase and the origin of high coercivity in this compound are identified, thus guiding further development of these materials for use as high performance permanent magnets without rare-earth elements.
Abstract: Solving the crystal structures of novel phases with nanoscale dimensions resulting from rapid quenching is difficult due to disorder and competing polymorphic phases. Advances in computer speed and algorithm sophistication have now made it feasible to predict the crystal structure of an unknown phase without any assumptions on the Bravais lattice type, atom basis, or unit cell dimensions, providing a novel approach to aid experiments in exploring complex materials with nanoscale grains. This approach is demonstrated by solving a long-standing puzzle in the complex crystal structures of the orthorhombic, rhombohedral, and hexagonal polymorphs close to the ${\mathrm{Zr}}_{2}{\mathrm{Co}}_{11}$ intermetallic compound. From our calculations, we identified the hard magnetic phase and the origin of high coercivity in this compound, thus guiding further development of these materials for use as high performance permanent magnets without rare-earth elements.

TL;DR: In this paper, a NaNbO3 photocatalyst with cubic-orthorhombic surface-junctions was synthesized by a polymerized-complex method.
Abstract: A NaNbO3 photocatalyst with cubic–orthorhombic surface-junctions was synthesized by a polymerized-complex method. Compared with cubic and orthorhombic NaNbO3, the activity of mixed-phase NaNbO3 is enhanced by 30% and 200% in reducing CO2 into CH4, respectively. The enhancement of photoactivity over mixed-phase NaNbO3 was attributed to the cubic–orthorhombic surface-junctions which improved the charge separation.

TL;DR: In this paper, structural phase transition, narrow band gap (Eg), and room-temperature ferromagnetism have been observed in the [KNbO3]1−x[BaNi1/2Nb1/ 2O3−δ]x (KBNNO) ceramics.
Abstract: Structural phase transition, narrow band gap (Eg), and room-temperature ferromagnetism (RTFM) have been observed in the [KNbO3]1−x[BaNi1/2Nb1/2O3−δ]x (KBNNO) ceramics. All the samples have single phase perovskite structure, but exhibit a gradual transition behaviour from the orthorhombic to a cubic structure with the increase of x. Raman spectroscopy analysis not only corroborates this doping-induced change in normal structure but also shows the local crystal symmetry for x ≥ 0.1 compositions to deviate from the idealized cubic perovskite structure. A possible mechanism for the observed specific changes in lattice structure is discussed. Moreover, it is noted that KBNNO with compositions x = 0.1–0.3 have quite narrow Eg of below 1.5 eV, much smaller than the 3.2 eV band gap of parent KNbO3 (KNO), which is due to the increasing Ni 3d electronic states within the gap of KNO. Furthermore, the KBNNO materials present RTFM near a tetragonal to cubic phase boundary. With increasing x from 0 to 0.3, the magnetis...

TL;DR: In this article, a pure and Cd-doped orthorhombic molybdenum trioxide (α-MoO 3 ) nanobelts with width of 200-800nm and length of several micrometers have been successfully synthesized by a facile and low temperature (120°C) hydrothermal method without any surfactant or template.
Abstract: Pure and Cd-doped orthorhombic molybdenum trioxide (α-MoO 3 ) nanobelts with width of 200–800 nm and length of several micrometers have been successfully synthesized by a facile and low temperature (120 °C) hydrothermal method without any surfactant or template. The crystal structure and morphology of the products were characterized by XRD and FESEM. The sensing measurements reveal that the synthesized samples not only exhibit high response to H 2 S but also small cross-sensing to other reducing gases. The change of intrinsic defects in Cd-doped sample is responsible for the enhancement of the sensing properties, which has been confirmed by the room temperature PL, Raman and XPS. The response transients of the sensors under different gas concentrations were measured and modeled using L–H heterogeneous reaction mechanism. Origin and mechanism of the enhanced gas sensing for 5 wt% Cd-doped sample were analyzed in detail according to the characteristic of PL and XPS.

TL;DR: In this paper, the main features of an original crystal modification of isotactic polypropylene (iPP) are described, which is obtained with a stereodefective or "anisotactic" iPP produced with a zirconene catalyst.
Abstract: The main features of an original crystal modification of isotactic polypropylene (iPP) are described. This form is obtained with a stereodefective or “an-isotactic” iPP produced with a zirconene catalyst by Rieger et al. [Macromolecules 1990, 23, 3559−3568]. In thin films, most of the material crystallizes as composite crystals made of α phase backbones with large amounts of γ phase overgrowths. The new form is nucleated by a crystal–crystal growth transition on parent α phase crystals. It is probably produced with only the most stereodefective part of the material. The single crystals formed in thin films are very similar to the αiPP elongated laths but do not display any of their overgrowths (α–α lamellar branching or α–γ epitaxial relationship). The electron diffraction evidence (hk0 and hk1 reflections accessed from flat-on and tilted single crystals, respectively) indicates an orthorhombic unit cell with parameters a = 12.50 A, b = 24.60 A, and c = 6.5 A that houses eight stems (space group Pccn).

The structure was solved and refined using synchrotron powder diffraction data, and Rietveld and density functional techniques. The most prominent feature of the structure is zigzag chains of N–H···Cl hydrogen bonds along the a-axis. The powder pattern has been submitted to the ICDD for inclusion in future releases of the Powder Diffraction File™.

TL;DR: A new noncentrosymmetric (NCS) ternary sulfide, Ba8Sn4S15, was synthesized by a conventional solid-state reaction as mentioned in this paper.
Abstract: A new noncentrosymmetric (NCS) ternary sulfide, Ba8Sn4S15, was synthesized by a conventional solid-state reaction. The compound crystallizes in the orthorhombic space group Pca21 (29), with unit cell parameters a = 28.727(5) A, b = 8.5220(14) A, c = 25.438(4) A, Z = 8, and V = 6227.5(18) A3. The major structure of Ba8Sn4S15 formed by isolated SnS4 tetrahedra and SnS3 pyramids features the zero-dimensional (0D) characteristic and shows the coexistence of divalent Sn(II) and tetravalent Sn(IV). The optical band gap of Ba8Sn4S15 is 2.31 eV with a wide transparent region of 0.73–25 μm. Importantly, the large dipole moment and the polarity enhancement of the SnS3 pyramid unit make Ba8Sn4S15 exhibit strong second harmonic generation (SHG) nonlinear optical response, which is about 10 times larger than that of the benchmark AgGaS2 in the particle size of 25–45 μm at the laser radiation wavelength of 2.05 μm with a non phase-matchable behavior. The density functional theory (DFT) studies confirm the experimental ...

TL;DR: In this article, the electronic properties of epitaxial orthorhombic SrIrO3 thin-films were investigated under compressive strain using transport measurements, optical absorption spectra, and magnetoresistance.
Abstract: Orthorhombic SrIrO3 is a correlated metal whose electronic properties are highly susceptible to external perturbations due to the comparable interactions of spin–orbit interaction and electronic correlation. We have investigated the electronic properties of epitaxial orthorhombic SrIrO3 thin-films under compressive strain using transport measurements, optical absorption spectra, and magnetoresistance. The metastable, orthorhombic SrIrO3 thin-films are synthesized on various substrates using an epi-stabilization technique. We have observed that as in-plane lattice compression is increased, the dc-resistivity (ρ) of the thin films increases by a few orders of magnitude, and the dρ/d T changes from positive to negative values. However, optical absorption spectra show Drude-like, metallic responses without an optical gap opening for all compressively strained thin films. Transport measurements under magnetic fields show negative magnetoresistance at low temperature for compressively strained thin-films. Our results suggest that weak localization is responsible for the strain-induced metal–insulator transition for the orthorhombic SrIrO3 thin-films.

TL;DR: In this article, the effect of Er-doped concentration on the crystal structure and on the ferroelectric and leakage current properties of BiFeO3 thin films were studied in detail.
Abstract: Multiferroic pure and Er-doped BiFeO3 thin films were prepared using a sol–gel technique. The effect of Er-doped concentration on the crystal structure and on the ferroelectric and leakage current properties of BiFeO3 films were studied in detail. The study showed the enhanced ferroelectric polarization and reduced leakage current density that occurred after doping Er. Such improved ferroelectric and leakage properties are attributed to ferroelectric distortion and to the change of leakage current conduction mechanisms derived from the structural transformation that occurred after doping Er. The rhombohedral structure of pure BiFeO3 transforms to the coexistence of tetragonal and orthorhombic symmetry structure as Er-doped concentration x increased gradually to 0.15, then to the orthorhombic structure when x = 0.20. The present work provides an easy method to decrease the leakage current and improve the ferroelectric properties of BiFeO3 films.

TL;DR: In this article, a modified stretched network model was employed to analyze strain-temperature equivalence on nucleation in FIC, which reveals that flow not only induces entropic reduction of initial melt, but also modifies the free energies of the final states.
Abstract: Extension-induced crystallization under near-equilibrium condition has been studied in a series of lightly cross-linked high density polyethylene (XL-HDPE) with a combination of extensional rheology and in situ synchrotron radiation small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) measurements. According to crystal morphology and structure, four regions were defined in strain-temperature space, namely “orthorhombic lamellar crystal” (OLC), “orthorhombic shish crystal” (OSC), “hexagonal shish crystal” (HSC) and “oriented shish precursor” (OSP), respectively. This indicates that flow not only induces entropic reduction of initial melt, but also modifies the free energies of the final states, which is overlooked in the classical stretched network model (SNM) for flow induced crystallization (FIC). Incorporating the free energies of various final states, a modified SNM is developed and employed to analyze strain-temperature equivalence on nucleation in FIC, which reveals that the cr...

TL;DR: LiNbO3-type ScFeO3 is successfully obtained, a metastable phase converted from the orthorhombic perovskite formed under 15 GPa at elevated temperatures, providing a general and versatile strategy to create materials in which ferroelectricity and ferromagnetism coexist at high temperatures.
Abstract: Multiferroic materials have been the subject of intense study, but it remains a great challenge to synthesize those presenting both magnetic and ferroelectric polarizations at room temperature. In this work, we have successfully obtained LiNbO3-type ScFeO3, a metastable phase converted from the orthorhombic perovskite formed under 15 GPa at elevated temperatures. A combined structure analysis by synchrotron X-ray and neutron powder diffraction and high-angle annular dark-field scanning transmission electron microscopy imaging reveals that this compound adopts the polar R3c symmetry with a fully ordered arrangement of trivalent Sc and Fe ions, forming highly distorted ScO6 and FeO6 octahedra. The calculated spontaneous polarization along the hexagonal c-axis is as large as 100 μC/cm2. The magnetic studies show that LiNbO3-type ScFeO3 is a weak ferromagnet with TN = 545 K due to a canted G-type antiferromagnetic ordering of Fe3+ spins, representing the first example of LiNbO3-type oxides with magnetic order...
