Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Distinct moiré Exciton dynamics in WS2/ WSe2 heterostructure
Feng Kai, Xiong Wang, Yiqin Xie +6
This letter reports a time resolved pump-probe reflectance spectroscopic study on moiré excitons in a twisted monolayer WS2/WSe2 heterostructure. By probing at the resonant energie…
Förster valley-orbit coupling and topological lattice of hybrid moiré excitons
Huiyuan Zheng, Ci Li, Hongyi Yu +1
Hybrid exciton in moiré superlattices of two-dimensional (2D) semiconductors inherits the electric dipole, strong moiré trapping, and stacking optical selection rules from its inte…
Phonons of electronic crystals in two-dimensional semiconductor moiré patterns
Hongyi Yu, Jiyong Zhou
We theoretically studied the phonon properties of the triangular-, stripe- and honeycomb-type electronic crystals recently found in two-dimensional semiconductor moiré patterns. By…
Distinct moiré textures of in-plane electric polarizations for distinguishing moiré origins in homobilayers
Hongyi Yu, Ziheng Zhou, Wang Yao
In binary compound 2D insulators/semiconductors such as hexagonal boron nitride (hBN), the different electron affinities of atoms can give rise to out-of-plane electric polarizatio…
Waveguiding valley excitons in monolayer transition metal dicalcogenides by dielectric interfaces in the substrate
Xu-Chen Yang, Hongyi Yu, Wang Yao
In monolayers of the semiconducting transition metal dichalcogenides, the electron-hole exchange interaction splits the exciton dispersion into a massive transverse branch, and a l…
