Is p-type doping in TeO2 feasible?
Zewen Xiao, Chen Qiu, Su-Huai Wei +1
Wide-bandgap two-dimensional (2D) beta-TeO2 has been reported as a high-mobility p-type transparent semiconductor (Nat. Electron. 2021, 4, 277-283), attracting significant attentio…
Ultrathin quantum light source enabled by a nonlinear van der Waals crystal with vanishing interlayer-electronic-coupling
Qiangbing Guo, Xiao-Zhuo Qi, Meng Gao +19
Interlayer electronic coupling in two-dimensional (2D) materials enables tunable and emergent properties by stacking engineering. However, it also brings significant evolution of e…
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…
