Large piezoelectric coefficients combined with high electron mobilities in Janus monolayer XTeI (X=Sb and Bi): a first-principle study

22 Oct 2019 Guo San-Dong Guo Xiao-Shu Liu Zhao-Yang Quan Ying-Ni

The absence of both the inversion symmetry and out-of-plane mirror symmetry together with spin-orbit coupling (SOC) can induce novel electronic and piezoelectric properties. In this work, the piezoelectric properties along with carrier mobilities of Janus monolayer XTeI (X=Sb and Bi) are studied by density functional theory (DFT)... (read more)
