Claim:
1. An electronic device comprising: a carbon layer including graphene; a thin film layer formed on the carbon layer; a current cutoff layer formed on the thin film layer; a channel layer formed on the current cutoff layer; and a source electrode and a drain electrode formed on the channel layer, wherein the carbon layer, the thin film layer, the current cutoff layer and the channel layer are stacked sequentially; and the current cutoff layer is formed of an insulating material or a material having a higher bandgap than the channel layer; wherein the electronic device has at least one of the following features: (i) a plurality of structures grown upward from the carbon layer, wherein the structures are micro-scale or nano-scale structures, and the thin film layer covers the structures; and (ii) the channel layer formed of any one of a pair of MgxZn1-xO and ZnO, a pair of AlxGa1-xN and GaN, a pair of AlxGa1-xAs and GaAs, and a pair of Si and Si1-xGex.
