Energy renormalizations of resident carriers and excitons in transition metal dichalcogenide monolayers
Dinh Van Tuan, Junghwan Kim, Hanan Dery
Energy renormalizations of resident carriers and excitons are studied theoretically, and compared with recent experiments of electrostatically-doped WSe monolayers. The calcula…
Ten-valley excitonic complexes in charge-tunable monolayer WSe
Alain Dijkstra, Amine Ben Mhenni, Dinh Van Tuan +10
Excitons dominate the optical response of two-dimensional (2D) semiconductors. Strong interactions produce peculiar excitonic complexes, which provide a testing ground for exciton…
High luminescence efficiency of multi-valley excitonic complexes in heavily doped WSe2 monolayer
Sébastien Roux, Tilly Guyot, Abraao Cefas Torres-Dias +9
Monolayers of group-VI transition-metal dichalcogenides (TMDs) are two-dimensional semiconductors that exhibit exceptionally strong light-matter coupling yet typically suffer from…
Excitons in moiré superlattices with disordered electrons
Junghwan Kim, Dinh Van Tuan, Hanan Dery
Moiré superlattices in transition metal dichalcogenides (TMDs) heterobilayers exhibit various correlated insulating states driven by long-range Coulomb interactions, and these sta…
Excitons in fractionally-filled moiré superlattices
Junghwan Kim, Hanan Dery, Dinh Van Tuan
Long-range Coulomb forces give rise to correlated insulating states when charge particles populate a moiré superlattice at certain fractional filling factors. Such behavior is cha…
