Buried triple-gate structures for advanced field-effect transistor devices
A buried triple-gate (BTG) structure with three independently controllable gates. Optimization of the BTG structure for graphene visibility by computer simulation. Fabrication of a 30nm wide and 5.5microns long graphene nanoribbon on the BTGs. Electrostatic n-p doping showing band-to-band tunneling in graphene at low T.
