Electrical Characteristics of Molybdenum Disulfide Flakes Produced by Liquid Exfoliation

Abstract

Semiconducting 2D MoS2 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 MoS2 flakes. Thus, scalable liquid-phase exfoliation of layered semiconductor compounds can yield novel materials with potential uses in future electronic devices.
