Orbital Engineering in Three Dimensional Halide Perovskites towards Two Dimensional Properties with Strong Anisotropy
Gang Tang, Zewen Xiao, Jiawang Hong
The discovery of double perovskites A2B(I)B(III)X6 (A=monovalent cation; B(I)/B(III) = metal cation; X = halogen) as Pb(II)-free alternatives has attracted widespread attention, ma…
First-Principles Understanding of the Electronic Band Structure of Copper-Antimony Halide Perovskite: The Effect of Magnetic Ordering
Xiaoming Wang, Weiwei Meng, Zewen Xiao +3
We report the understanding of the electronic band structure of perovskite through first-principles density-functional theory calculations. We find that the mos…

n-type conversion of SnS by isovalent ion substitution: Geometrical doping as a new doping route
Fan-Yong Ran, Zewen Xiao, Yoshitake Toda +3
Tin monosulfide (SnS) is a naturally p-type semiconductor with a layered crystal structure, but no reliable n-type SnS has been obtained by conventional aliovalent ion substitution…
Narrow Bandgap in beta-BaZn2As2 and Its Chemical Origins
Zewen Xiao, Hidenori Hiramatsu, Shigenori Ueda +7
Beta-BaZn2As2 is known to be a p-type semiconductor with the layered crystal structure similar to that of LaZnAsO, leading to the expectation that beta-BaZn2As2 and LaZnAsO have si…
