Twisted-light-induced exciton wave packets in transition-metal dichalcogenide monolayers
Guan-Hao Peng, Oscar Javier Gomez Sanchez, Wei-Hua Li +2
We present a comprehensive theoretical investigation of the photo-generated excitons in transition-metal dichalcogenide monolayers (TMD-ML's) by Laguerre-Gaussian beams, a celebrat…
Inherently high valley polarizations of momentum-forbidden dark excitons in transition-metal dichalcogenide monolayers
Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2
High degree of valley polarization of optically active excitons in transition-metal dichalcogenide monolayers (TMD-MLs) is vital in valley-based photonic applications but known to…
Symmetry governed valley-pseudospin textures of the full-zone excitonic bands of transition-metal dichalcogenide monolayers
Ping-Yuan Lo, Guan-Hao Peng, Wei-Hua Li +2
Preserving a high degree of valley polarization of excitons in photo-excited transition-metal dichalcogenide monolayers (TMD-MLs) is desirable for the valley-based photonic applica…
Distinctive signatures of the spin- and momentum-forbidden dark exciton states in the photo-luminescences of strained WSe monolayers under thermalization
Guan-Hao Peng, Ping-Yuan Lo, Wei-Hua Li +5
With the both spin and valley degrees of freedom, the low-lying excitonic spectra of photo-excited transition-metal dichalcogenide monolayers (TMDC-MLs) are featured by rich fine s…
