Engineering topological exciton structures in two-dimensional semiconductors by a periodic electrostatic potential
Na Zhang, Wang Yao, Hongyi Yu
We propose to engineer topological exciton structures in layered transition metal dichalcogenides through hybridizing different Rydberg states, which can be induced by a periodic e…

Twistronics and moiré superlattice physics in 2D transition metal dichalcogenides
Dawei Zhai, Hongyi Yu, Wang Yao
The moiré superlattices formed by stacking 2D semiconducting transition metal dichalcogenides (TMDs) with twisting angle or lattice mismatch have provided a versatile platform wit…

Pressure Tuning of Layer-hybridized Excitons in Trilayer WSe2
Xuan Zhao, Jing Song, Wenqi Xiong +8
We demonstrate dynamic pressure tuning (0-6.6 GPa) of layer-hybridized excitons in AB-stacked trilayer WSe via diamond-anvil-cell-integrated reflectance spectroscopy. Pressure-…
