Abstract

Semiconducting 2D MoS ₂ flakes produced by liquid phase exfoliation are contacted with metal electrodes, which are defined by electron beam lithography. Electrical analysis of the metal-semiconductor-metal structures reveals high mobilities for individual MoS ₂ flakes. Thus, scalable liquid-phase exfoliation of layered semiconductor compounds can yield novel materials with potential uses in future electronic devices.
