Envelope function method for electrons in slowly-varying inhomogeneously deformed crystals
Wenbin Li, Xiaofeng Qian, Ju Li
We develop a new envelope-function formalism to describe electrons in slowly-varying inhomogeneously strained semiconductor crystals. A coordinate transformation is used to map a d…

Quantum Spin Hall Effect and Topological Field Effect Transistor in Two-Dimensional Transition Metal Dichalcogenides
Xiaofeng Qian, Junwei Liu, Liang Fu +1
We report a new class of large-gap quantum spin Hall insulators in two-dimensional transition metal dichalcogenides, namely, MX with M=(Mo, W) and X=(S, Se, and Te), whose topo…

Topological Crystalline Insulator Nanomembrane with Strain-Tunable Band Gap
Xiaofeng Qian, Liang Fu, Ju Li
The ability to fine-tune band gap and band inversion in topological materials is highly desirable for the development of novel functional devices. Here we propose that the electron…
