Abstract

When electron-hole pairs are excited in a semiconductor, it is a priori not clear if subsequent relaxation leads to a gas of bound excitons or to an interacting plasma of unbound electrons and holes. Usually, the exciton phase is associated with low temperatures. In atomically thin transition metal dichalcogenide (TMDC) semiconductors, excitons are particularly important even at room temperature due to strong Coulomb interaction and a large exciton density of states.
