Trion fine structure and coupled spin–valley dynamics in monolayer tungsten disulfide

Monolayer transition metal dichalcogenides are promising materials for valleytronics applications. Here, the authors study WS2samples using photoluminescence spectroscopy and time-resolved Kerr-rotation measurements at low temperatures, gaining insight into the valley dynamics of excitons.
