hBN-encapsulated Group-VI TMDC van der Waals Heterostructures : Fabrication and Optical properties

Not Accessible

Your library or personal account may give you access


Two-dimensional (2D) semiconductors, including MoS2, WS2, MoSe2, etc., have provided a fascinating opportunity to explore optical properties in 2 dimensions. In particular, van der Waals (vdW) heterostructures composed of these 2D semiconductors, such as WS2/MoS2, offer a novel platform for optical physics, where strong inter-layer interaction drastically alters optical transitions. To explore the intrinsic properties of TMDC vdW heterostructures, high-quality samples are indispensable. Here, we report preparation and optical properties of high-quality vdW heterostructure (WS2/MoS2) which are fully encapsulated by hexagonal boron nitride (hBN) (Fig. 1).
