Light-matter interactions in atomically thin transition metal dichalcogenides by Zhao, Jiaxin

“…In Chapter 3, we start with investigations on the carrier dynamics and many-body interactions in monolayer TMDs by employing transient absorption spectroscopy. As for monolayer tungsten disulphide (WS2), the exciton energy renormalization is revealed with a distinct red-blue-red shift upon above-bandgap optical excitations. …”
