When electron-hole pairs are excited in a semiconductor, it is a priori not clear if they form a
plasma of unbound fermionic particles or a gas of composite bosons called excitons …

A key feature of monolayer semiconductors, such as transition-metal dichalcogenides, is the
poorly screened Coulomb potential, which leads to a large exciton binding energy (E b) and …
