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 with…
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…
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-…
Chiral phonons of honeycomb-type bilayer Wigner crystals
Dingrui Yang, Lingyi Li, Na Zhang +1
We theoretically investigated the chiral phonons of honeycomb-type bilayer Wigner crystals recently discovered in van der Waals structures of layered transition metal dichalcogenid…
Interlayer couplings in homobilayer structures of MSi2X4 (M = Mo/W, X = N/P/As)
Qian Wang, Na Zhang, Hongyi Yu
We investigated the interlayer coupling effect in homobilayer structures of MSi2X4 with M = Mo/W and X = N/P/As. Through the combination of first-principles calculations and analyt…
Dipolar interactions enhanced by two-dimensional dielectric screening in few-layer van der Waals structures
Yuhang Hou, Hongyi Yu
We theoretically examined how the dielectric screening of two-dimensional layered materials affects the dipolar interaction between interlayer excitons in few-layer van der Waals s…
