Abstract: Transition metal dichalcogenides can be prepared as atomically thin monolayers with unique optical and electronic properties that open up numerous (opto-)electronic applications. In this thesis, we performed time-resolved laser spectroscopy techniques to unravel the underlying physical processes, namely the thermalization, cooling and recombination as well as separation of charge carriers, plus coherent motions of the crystal lattice.

Übergangsmetall-Dichalkogenide können als atomar dünne Monolagen mit einzigartigen Eigenschaften präpariert werden, was zahlreiche Anwendungsmöglichkeiten in der (Opto-)Elektronik eröffnet. In dieser Arbeit haben wir zeitaufgelöste Laserspektroskopietechniken verwendet, um die zugrundeliegenden physikalischen Prozesse aufzudecken, als da sind die Thermalisierung, Abkühlung und Rekombination sowie Trennung von Ladungsträgern, plus kohärente Schwingungsbewegungen des Kristallgitters.
