Defects activated photoluminescence in two-dimensional semiconductors: interplay between bound, charged, and free excitons

Defects activated photoluminescence in two-dimensional semiconductors: interplay between bound, charged, and free excitons

Point defects in semiconductors can trap free charge carriers and localize excitons. The interaction between these defects and charge carriers becomes stronger at reduced dimensionalities, and is expected to greatly influence physical properties of the hosting material. We investigated effects of an...
