Signatures of valley drift in the diversified band dispersions of bright, gray, and dark excitons in MoS2 monolayers under uni-axial strains
Ching-Hung Shih, Guan-Hao Peng, Ping-Yuan Lo +4
We present a comprehensive theoretical investigation of the strain-modulated excitonic properties of uni-axially strained transition-metal dichalcogenide monolayers (TMD-MLs) by so…

Enhanced photo-excitation and angular-momentum imprint of gray excitons in WSe monolayers by spin-orbit-coupled vector vortex beams
Oscar Javier Gomez Sanchez, Guan-Hao Peng, Wei-Hua Li +3
A light beam can be spatially structured in the complex amplitude to possess orbital angular momentum (OAM), which introduces a new degree of freedom alongside the intrinsic spin a…
