▎ 摘 要
NOVELTY - The FET has a gate dielectric layer placed at upper and lower sides of a channel layer. A substrate is formed with the gate dielectric layer. A source electrode and a drain electrode are placed at two ends of the channel layer that is made of a single layer or double layer graphite nano-belt. Thickness of a top part of the gate dielectric layer is about 30nm. USE - Graphene nano-belt FET. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of graphene nano-belt FET. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene nano-belt FET.
