The edge-to-edge connected metal-semiconductor junction (MSJ) for two-dimensional (2D) transistors has the potential to reduce contact length while improving performance of devices. However, typical 2D materials are thermally and chemically unstable, which impedes reproducible achievement high-quality edge contacts. Here we present a scalable synthetic strategy fabricate low-resistance contacts atomic using stable metal, PtTe2. use PtTe2 as an epitaxial template enables lateral growth...
