Van der Waals MoS₂/VO₂ heterostructure junction with tunable rectifier behavior and efficient photoresponse.

ABSTRACT: Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of materials. In parallel, strongly correlated functional oxides have emerged, having the ability to show reversible insulator-to-metal (IMT) phase transition by collapsing their electronic bandgap under a certain external stimulus. Here, we report for the first time the electronic and optoelectronic characterization of ultra-thin n-n heterojunctions fabricated using deterministic assembly of multilayer molybdenum disulphide (MoS₂) on a phase transition material, vanadium dioxide (VO₂). The vdW MoS₂/VO₂
