Spatial extension of exciton states in van der Waals heterostructure

Poster-In-person

Abstract

We studied narrow lines in emission spectra of spatially indirect excitons, also known as interlayer excitons, in MoSe2/WSe2 van der Waals heterostructure. We found that the narrow lines extend over distances reaching several micrometers. The macroscopic spatial extension of exciton states corresponding to narrow lines indicates ordering in the local environment of excitons showing that excitons are confined in moiré potential with a weak disorder.
