Abstract: We report unique electrical anisotropy and dielectric properties of graphene oxide (GO) thin films, which allow facile implementation of GO-based monolithic field effect transistors (FETs). We demonstrate that exposure of GO films to hydrogen plasma leads to self-limiting reduction of only the uppermost layers such that a semiconductor-on-insulator type heterostructure is realized. In such heterostructures, the reduced uppermost layers and the unmodified bulk GO layers serve as the channel and gate dielectric components, respectively, of a thin film FET. © 2013 American Institute of Physics.
