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.
