Two-Dimensional Coherent Spectroscopy of Transition Metal Dichalcogenides



Galan Moody


Optical two-dimensional coherent spectroscopy is an extremely useful tool for examining the structure and dynamics of semiconductors. The appeal of the technique is in its ability to resolve both individual-emitter and ensemble-averaged properties of disordered systems, reveal the nature of coupling between transitions, and elucidate many-body interactions. In this article, the basic principles of the technique are introduced, and its capabilities are illustrated with recent experiments that have examined optical decoherence, energy transfer, and multi-particle interactions in monolayer transition metal dichalcogenides.
