Synthesis of Artificial 2D Lattices of Monolayer Multi-junctions

ORAL

Abstract

Recently, monolayers of transition metal dichalcogenides (TMDs) are ideal building blocks for constructing artificial 2D lattices. Heterostructures with multi-junctions of more than two monolayer TMDs are intriguing for exploring new physics. Here, the laterally stitched TMDs and the vertically stacked monolayers are constructed. A low growth temperature synthesis and a clean transfer method are developed for high quality hetero-interfaces. With optimized parameters, atomically sharp interfaces are successfully achieved in the synthesis of in-plane artificial lattices of the WS2/WSe2/MoS2. Characterizations of the hetero-interfaces are presented.
