Nonlinear optics in the electron-hole continuum in 2D semiconductors: two-photon transition, second harmonic generation and valley current injection
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate two-photon transitions to the electron-hole scattering continuum in monolayer transition-metal dichalcogenides, and identify two contributions to this nonlinear opti…

Coulomb effects on topological band inversion in the moiré of WSe/BAs heterobilayer
Qizhong Zhu, Qingjun Tong, Huazheng Sun +2
Quantum spin Hall (QSH) insulator with large gap is highly desirable for potential spintronics application. Here we realize electrically tunable QSH insulator with large gap in van…
