Exploitation of fundamental properties of atomically thin (two-dimensional, 2D) semiconductors – particularly those from the transition metal dichalcogenide (TMD) family – for electronics will require ultra-clean contacts with resistances approaching the quantum limit. The lack of high quality, low contact resistance p- and n-type contacts on 2D semiconductors has limited progress in next generation of low power devices such as the tunnel field effect transistors. In this presentation, we summarize strategies and provide guidance for making clean van der Waals (vdWs) contacts on mono-layered semiconductors.
