Abstract

See full text

An electronic device comprises an insulator, a local first gate embedded in the insulator with a top surface of the first gate being substantially coplanar with a surface of the insulator, a first dielectric layer formed over the first gate and insulator, and a channel. The channel comprises a bilayer graphene layer formed on the first dielectric layer. The first dielectric layer provides a substantially flat surface on which the channel is formed. A second dielectric layer formed over the bilayer graphene layer and a local second gate formed over the second dielectric layer. Each of the local first and second gates is capacitively coupled to the channel of the bilayer graphene layer. The local first and second gates form a first pair of gates to locally control a first portion of the bilayer graphene layer.
