Monolayer indium selenide: an indirect bandgap material exhibits efficient brightening of dark excitons
Abstract Atomically thin indium selenide (InSe) exhibits a sombrero-like valence band, leading to distinctive excitonic behaviors. It is known that the indirect band gap of atomically thin InSe leads to a weak emission from the lowest-energy excitonic state (A peak). However, the A peak emission of...
