The rotating excitons in two-dimensional materials: Valley Zeeman effect and chirality
Yu Cui, Xin-Jun Ma, Jia-Pei Deng +4
We propose the rotational dynamics of the intralayer and interlayer excitons with their inherent momenta of inertia in the monolayer and bilayer transition metal dichalcogenides, r…
Theory of all-coupling angulon for molecules rotating in many-body environment
Yi-Yan Liu, Yu Cui, Xiao-Zhe Zhang +3
The formation of angulon, stemming from the rotor (molecule or impurity) rotating in the quantum many-body field, adds a new member in the quasiparticle's family and has aroused in…
Charge carriers trapping by the full-configuration defects in metal halide perovskites quantum dots
Xiao-Yi Liu, Yu Cui, Jia-Pei Deng +6
Metal halide perovskites quantum dots (MHPQDs) have aroused enormous interesting in the photovoltaic and photoelectric because of their marvelous properties and size characteristic…
Infrared optical absorption of Frohlich polaron in metal halide perovskites
Yu Cui, Xiao-Yi Liu, Xu-Fei Ma +4
The formation of Frohlich polaron in metal halide perovskites, arising from the charge carrierlongitudinal optical (LO) phonon coupling, has been proposed to explain their exceptio…
Self-trapped interlayer excitons in van der Waals heterostructures
Jia-Pei Deng, Hong-Juan Li, Xu-Fei Ma +5
The self-trapped state (STS) of interlayer exciton (IX) has been aroused enormous interesting owing to their significant impact on the fundamental properties of the van derWaals he…
Correction of exciton binding energy in monolayer transition metal dichalcogenides
Zi-Wu Wang, Yao Xiao, Wei-Ping Li +2
We theoretically investigate the corrections of exciton binding energy in monolayer transition metal dichalcogenides (TMDs) due to the exciton-optical phonon coupling in the Fr$\dd…
