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 stat…
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…
Breakdown of the static dielectric screening approximation of Coulomb interactions in atomically thin semiconductors
Amine Ben Mhenni, Dinh Van Tuan, Leonard Geilen +10
Coulomb interactions in atomically thin materials are uniquely sensitive to variations in the dielectric screening of the environment, which can be used to control quasiparticles a…
Tetrons, pexcitons, and hexcitons in monolayer transition-metal dichalcogenides
Dinh Van Tuan, Hanan Dery
We present a comprehensive theoretical analysis of composite excitonic states in doped transition-metal dichalcogenide monolayers. Making use of the pair distribution function, we…
Turning many-body problems to few-body ones in photoexcited semiconductors using the stochastic variational method in momentum space, SVM-k
Dinh Van Tuan, Hanan Dery
We develop an efficient computational technique to calculate composite excitonic states in photoexcited semiconductors through the stochastic variational method (SVM). Many-body in…
