TL;DR: In this paper, polycrystalline samples of the modified Pb(Zr1−x Tix)O3 (PZT) composition, with representative formula Pb0.92(LazBi1−z)0.98O3, a family of relaxor ferroelectrics, were prepared via the chemical route with z = 0.3, 0.6 and 0.9.
Abstract: Polycrystalline samples of the modified Pb(Zr1−x Tix)O3 (PZT) composition, with representative formula Pb0.92(LazBi1−z)0.08(Zr0.65Ti0.35)0.98O3 (PLBZT), a family of relaxor ferroelectrics, were prepared via the chemical route with z = 0.3, 0.6 and 0.9. Crystalline phases of powders calcined at different temperatures and the microstructure of the sintered pellets were investigated by x-ray diffraction (XRD) analysis and scanning electron microscopy, respectively. XRD confirms the result obtained by differential scanning calorimetry. The XRD profile shows that the samples having z = 0.9 and 0.6 do not exhibit a pyrochlore phase, whereas the samples with z = 0.3, have 3% of the pyrochlore phase. Microstructural analysis suggests that the shape of grains and intergranular residual pores are modified upon La doping. The dielectric constant and dielectric losses were measured as a function of frequency at room temperature for different frequencies starting from 0.1 kHz to 1 MHz. The dielectric constant was found to be strongly influenced by frequency whereas the Curie temperature remained almost the same. Finally, we conclude that the dielectric constant, loss and activation energy of PLBZT strongly suggest that these compounds are suitable for the preparation of high value capacitors and may be good candidates for device applications.

TL;DR: In this article, the authors investigated low-temperature transport through single InAs quantum wells and broken-gap InAs/GaSb double quantum well systems and confirmed the presence of edge conduction.
Abstract: We investigate low-temperature transport through single InAs quantum wells and broken-gap InAs/GaSb double quantum wells Nonlocal measurements in the regime beyond bulk pinch-off confirm the presence of edge conduction in InAs quantum wells The edge resistivity of $1--2\mathrm{k}\mathrm{\ensuremath{\Omega}}/\ensuremath{\mu}\mathrm{m}$ is of the same order of magnitude as edge resistivities measured in the InAs/GaSb double quantum well system Measurements in a tilted magnetic field suggests an anisotropy of the conducting regions at the edges with a larger extent in the plane of the sample than normal to it Finger-gate samples on both material systems shine light on the length dependence of the edge resistance with the intent to unravel the nature of edge conduction in InAs/GaSb coupled quantum wells

TL;DR: In this paper, it was shown that the chemical short-range order (CSRO) of amorphous Zr 3 Fe studied by Mossbauer spectroscopy is similar to the CSRO of metastable crystalline Zr3 Fe formed during crystallization.
