Bismuth and Antimony Based Oxyhalides and Chalcohalides as Potential Optoelectronic Materials
Zhao Ran, Xinjiang Wang, Yuwei Li +5
In the last decade the ns cations (e.g., Pb and Sn) based halides have emerged as one of the most exciting new classes of optoelectronic materials, as exemplified…
Ideal Bandgap in a 2D Ruddlesden-Popper Perovskite Chalcogenide for Single-junction Solar Cells
Shanyuan Niu, Debarghya Sarkar, Kristopher Williams +12
Transition metal perovskite chalcogenides (TMPCs) are explored as stable, environmentally friendly semiconductors for solar energy conversion. They can be viewed as the inorganic a…
Frustrated structural instability in superconducting quasi-one-dimensional KCrAs
Keith M. Taddei, Guangzong Xing, Jifeng Sun +6
We present neutron total scattering and density functional theory studies on quasi-one-dimensional superconducting KCrAs revealing a frustrated structural instability.…
Optical and Electronic Properties of Doped -type CuI: Explanation of Transparent Conductivity from First Principles
Y. Li, J. Sun, D. J. Singh
We report properties of the reported transparent conductor CuI, including the effect of heavy -type doping. The results, based on first principles calculations, include analysis…
Tunability of electronic and optical properties of the Ba-Zr-S system via dimensional reduction
Y. Li, D. J. Singh
Transition metal sulfide perovskites offer lower band gaps and greater tunability than oxides, along with other desirable properties for applications. Here we explore dimensional r…
Properties of the ferroelectric visible light absorbing semiconductors: SnPS and SnPSe
Yuwei Li, David J. Singh
Ferroelectrics with suitable band gaps have recently attracted attention as candidate solar absorbing materials for photovoltaics. The inversion symmetry breaking may promote the s…
