How much range of band gap for nickel oxide?5 answersThe band gap of nickel oxide (NiO) thin films varies in the range of 2.86 eV to 3.92-3.68 eV. The sol-gel method produced NiO films with an optical band gap of 2.86 eV. The hydrothermally obtained film had an optical band gap of 3.14 eV. The band gap values of NiO thin films prepared by sol-gel dip-coating technique ranged from 3.69 eV to 3.27 eV. Additionally, the optical band gap of NiO nanoparticles decreased from 3.65 eV to 3.38 eV with increasing cobalt (Co) concentration from 0 to 5%. Therefore, the range of band gap for nickel oxide is approximately 2.86 eV to 3.92-3.68 eV, depending on the synthesis method and the presence of dopants such as Co.
What is the bandgap of Cs2AgBiBr6 perovskite?4 answersThe bandgap of Cs2AgBiBr6 perovskite can be tuned from 2.18 eV to 1.61 eV through hydrogenation treatment. The wide and indirect bandgap of Cs2AgBiBr6 film limits its light absorption ability, resulting in a lower photoelectronic conversion efficiency (PCE). However, by using a hydrogenation method, the highest PCE of hydrogenated Cs2AgBiBr6 perovskite solar cell has been improved up to 6.58%. The interstitial doping of atomic hydrogen in Cs2AgBiBr6 lattice not only adjusts its valence and conduction band energy levels, but also optimizes the carrier mobility and carrier lifetime. The bandgap of Cs2AgBiBr6 can also be increased progressively with increasing Cl content in anion-mixed Cs2AgBiBr6−xClx compounds.
Band gap of anodization wo3 by fluoride??5 answersThe band gap of anodized tungsten trioxide (WO3) can be influenced by the presence of fluoride ions. In the study by Lee et al., WO3-decorated TiO2 nanotube arrays were synthesized using an in situ anodization method with dissolved ammonium fluoride. The incorporation of WO3 onto TiO2 nanotubes improved the mercury removal performance due to improved charge separation and decreased charge carrier recombination. Additionally, the band gap of WO3 can be reduced by doping it with NH4 through NH4OH treatment. The incorporation of NH4 into WO3 leads to a reduction in the band gap, lowering the onset potential and increasing the current density for the oxygen evolution reaction under illumination. Therefore, the presence of fluoride ions and NH4 doping can affect the band gap of anodized WO3.
What is a band gap?5 answersA band gap is an important property of a semiconductor material. It refers to the energy range in which the material does not allow the flow of electrons or light. The band gap determines the material's ability to absorb and emit specific wavelengths of light, which is crucial for optoelectronic devices such as solar cells and light-emitting diodes. The band gap can be tuned under external parameters, allowing for a wider range of applications in these devices. Pseudo-gaps are regions of very low density of states that have been linked to novel phenomena like high temperature superconductivity. They can be induced in a lattice by introducing boundaries and occur due to the interference between asymmetric pumping channels. Pseudo-gaps have profound implications for topological bulk-boundary correspondences and can host symmetry-protected mid-gap modes.
Why is the band gap of TiO2 important?5 answersThe band gap of TiO2 is important because it determines the material's ability to absorb and emit light, which is crucial for various applications. Different factors can influence the band gap energy of TiO2, such as the crystalline phases, crystal size, and doping concentration. For example, the introduction of the Fe2O3 phase into TiO2 can decrease the band gap energy, allowing for better absorption of visible light. Similarly, H-substitution in graphdiyne (GDY) can increase the band gap energy, leading to improved charge separation and enhanced photocatalytic activity when GDY is hybridized with TiO2. Doping with Tb can also affect the band gap energy, with higher Tb concentrations resulting in lower band gap values. Understanding and controlling the band gap energy of TiO2 is essential for optimizing its performance in photocatalysis and other applications.
Why finding accurate band gap of inorganic semiconductors?3 answersFinding accurate band gaps of inorganic semiconductors is important for their effective use in optoelectronic and photonic devices. Theoretical calculations often underestimate band gaps, leading to incorrect predictions of material properties. Accurate band gap values are necessary for designing semiconductor devices with appropriate energy levels and dopant positioning. The ability to align valence band-top and conduction band-bottom is crucial for optimizing the performance of semiconductors in various applications. Experimental and theoretical results of band gaps can be challenging and tricky, especially for compounds with mixed bonding character. The development of new theoretical approaches, such as the non-regular Tran and Blaha’s modified Becke–Johnson (nTB-mBJ) method, has shown promise in accurately reproducing band gaps of semiconductors. Accurate band gap values also facilitate band gap engineering, allowing for the tuning of semiconductor properties to meet specific device requirements.
