Abstract
Understanding the charge carrier dynamics in heterostructures of transition metal dichalcogenides (TMDs) is crucial for optimizing them for potential applications in electronic and optoelectronic devices. In this study, we investigate three different TMDs heterostructures using Raman spectroscopy and ultrafast pump-probe microscopy (UPPM). The carrier dynamics are discussed in relation to the stacking configuration of the MoS₂ and WS₂ layers as well as the quality of the layers.
