Observation of Strong Interlayer Couplings in WS<sub>2</sub>/MoS<sub>2</sub> Heterostructures via Low-Frequency Raman Spectroscopy

Van der Waals (vdW) heterostructures based on two-dimensional (2D) transition metal dichalcogenides (TMDCs), particularly WS<sub>2</sub>/MoS<sub>2</sub> heterostructures with type-II band alignments, are considered as ideal candidates for future functional optoelectronic appl...
