Patent ID: 8916405

Claim:
A method of fabricating a LED, comprising the steps of: providing a substrate; forming an insulator layer on the substrate, wherein the insulator layer has a bilayer configuration; after the insulator layer has been formed on the substrate, forming a first bottom gate and a second bottom gate embedded in the insulator layer such that the first bottom gate and the second bottom gate extend only part way through the insulator layer and a portion of the insulator layer separates the first bottom gate and the second bottom gate from the substrate; depositing a gate dielectric on the first and second bottom gates; depositing a carbon material directly on the gate dielectric over the first bottom gate and the second bottom gate, wherein the carbon material as deposited covers only a portion of the gate dielectric and serves as a channel region of the LED; and forming metal source and drain contacts directly on the gate dielectric and which cover a portion of, and are in contact with, the carbon material.
