Schottky barrier diodes (SBDs) with different carbon materials, namely pyrolytic carbon, glassy carbon and graphene have been investigated. The devices have been characterized structurally with HRTEM and Raman spectroscopy. From current-voltage measurements, diode parameters including the ideality factor, the Schottky barrier height and the series resistance are extracted. With graphene it is possible...
The remarkable properties of graphene have potential for numerous applications; however, their exploitation depends on its reliable production. The chemical vapour deposition (CVD) growth of graphene on metal surfaces has become one of the most promising strategies for the production of high quality graphene in a scaleable manner. Here, we discuss graphene growth on nickel (Ni) and copper (Cu) directly...
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...
