Intervalley electron-hole exchange interaction and impurity-assisted recombination of indirect excitons in WS and WSe monolayers
Pengke Li, Cedric Robert, Dinh Van Tuan +3
The variety of excitonic states in tungsten-based dichalcogenide monolayers stems from unique interplay between the spin and valley degrees of freedom. One of the exciton species i…
Relaxation and darkening of excitonic complexes in electrostatically-doped monolayer semiconductors: Roles of exciton-electron and trion-electron interactions
Min Yang, Lei Ren, Cedric Robert +5
We present photoluminescence measurements in monolayer WSe, which point to the importance of the interaction between charged particles and excitonic complexes. The theoretical…
Spin/Valley pumping of resident electrons in WSe2 and WS2 monolayers
Cedric Robert, Sangjun Park, Fabian Cadiz +14
Monolayers of transition metal dichalcogenides are ideal materials to control both spin and valley degrees of freedom either electrically or optically. Nevertheless, optical excita…
Valley Phonons and Exciton Complexes in a Monolayer Semiconductor
Minhao He, Pasqual Rivera, Dinh Van Tuan +10
The coupling between spin, charge, and lattice degrees of freedom plays an important role in a wide range of fundamental phenomena. Monolayer semiconducting transitional metal dich…
Exciton valley depolarization in monolayer transition-metal dichalcogenides
Min Yang, Cedric Robert, Zhengguang Lu +4
The valley degree of freedom is a sought-after quantum number in monolayer transition-metal dichalcogenides. Similar to optical spin orientation in semiconductors, the helicity of…
Virtual trions in the photoluminescence of monolayer transition-metal dichalcogenides
Dinh Van Tuan, Aaron M. Jones, Min Yang +2
Photoluminescence experiments from monolayer transition-metal dichalcogenides often show that the binding energy of trions is conspicuously similar to the energy of optical phonons…
