Side Gate Graphene and AlGaN/GaN Unipolar Nanoelectronic Devices
Three-terminal junction devices were realized in graphene grown heteroepitaxially on semiinsulating silicon carbide as well as in AlGaN/GaN heterostructures grown by MOCVD on sapphire containing a two dimensional electron gas. These nanoelectronic devices were fabricated using electron beam lithography. In both types of heterostructures room temperature electrical measurements revealed a pronounced nonlinear electrical behavior of the fabricated nanoelectronic devices. The obtained voltage rectification at room temperature demonstrates the feasibility of func-tional three-terminal junctions in heterostructures consisting of types of high carrier mobility struc-tures than classical III-V semiconductor heterostructures.
