Abstract:
Here, we report the first demonstration of atomically thin vertically stacked MoS2/WS2 heterostructures, achieved via a two-step chemical vapour deposition (CVD) growth process. Highly ordered stacking of heterostructure domains and patterned defects have been observed. Computations based on first principles have been performed to understand observed enhanced photoluminescence of the heterostructure.
