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…

Landau-level composition of bound exciton states in magnetic field
Dinh Van Tuan, Hanan Dery
We present a theory that studies the state composition of a bound exciton in magnetic field. Using a basis set made of products of free electron and hole wavefunctions in Landau ga…

Energy shifts and broadening of excitonic resonances in electrostatically-doped semiconductors
Hanan Dery, Cedric Robert, Scott A. Crooker +2
Tuning the density of resident electrons or holes in semiconductors provides crucial insight into the composition of excitonic complexes that are observed as absorption or photolum…
