Coexistence of intrinsic piezoelectricity and nontrivial band topology in monolayer InXO (X=Se and Te)

San-Dong Guo, Wen-Qi Mu, Yu-Tong Zhu +2

The combination of piezoelectricity with other unique properties (like topological insulating phase and intrinsic ferromagnetism) in two-dimensional (2D) materials is much worthy o…
