Abstract
A graphene device includes: a semiconductor substrate having a first region and a second region; a graphene layer on the first region, but not on the second region of the semiconductor substrate; a first electrode on a first portion of the graphene layer; a second electrode on a second portion of the graphene layer; an insulating layer between the graphene layer and the second electrode; and a third electrode on the second region of the semiconductor substrate. The semiconductor substrate has a tunable Schottky barrier formed by junction of the graphene layer and the semiconductor substrate.
