Abstract

Read online

Material interfaces are highly crucial to improve device performances. Here, the authors report interfacial reconstruction at the Au {001} substrate surface and the top MoS2 and WS2 monolayers due to the formation of a metastable interfacial Au4S4 phase. The reconstructed interface results in a p-type Schottky contact with reduced barrier height.
