Highly Anisotropic Excitons and Multiple Phonon Bound States in a Van der Waals Antiferromagnetic Insulator
Kyle Hwangbo, Qi Zhang, Qianni Jiang +9
Two-dimensional semiconducting systems, such as quantum wells and transition metal dichalcogenides, are the foundations to investigate low dimensional light-matter interactions. To…
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…
Optical selection rules for excitonic Rydberg series in the massive Dirac cones of hexagonal 2D materials
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate the optical transition selection rules for excitonic Rydberg series formed in massive Dirac cones. The entanglement of the exciton envelop function with the pseudosp…
