Coulomb potential screening via charged carriers and charge-neutral dipoles/excitons in two-dimensional case
Ke Xiao, Chi-Ming Kan, Stuart. S. P. Parkin +1
With the shrinking of dimensionality, Coulomb interactions play a distinct role in two-dimensional (2D) semiconductors owing to the reduced dielectric screening in the out-of-plane…
Exciton-exciton Interaction in Monolayer MoSe from Mutual Screening of Coulomb Binding
Ke Xiao, Tengfei Yan, Chengxin Xiao +7
The potential for low-threshold optical nonlinearity has received significant attention in the fields of photonics and conceptual optical neuron networks. Excitons in two-dimension…
In-Plane Electric Field Induced Orbital Hybridization of Excitonic States In Monolayer WSe2
Bairen Zhu, Ke Xiao, Siyuan Yang +3
The giant exciton binding energy and the richness of degrees of freedom make monolayer transition metal dichalcogenide an unprecedented playground for exploring exciton physics in…
