▎ 摘　　要

NOVELTY - The graphene device (100) comprises a gate electrode (160), a source electrode (140), a drain electrode (150) and a plasmonic pattern (170) that is formed on the gate electrode, where multiple penetration holes are formed in the gate electrode. A channel layer is formed with a drain electrode. A graphene sheet is formed between the source electrode and drain electrode. USE - Graphene device. ADVANTAGE - The graphene device comprises a gate electrode, a source electrode, a drain electrode and a plasmonic pattern that is formed on the gate electrode, where multiple penetration holes are formed in the gate electrode, and thus ensures simplified structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene device. Graphene device (100) Source electrode (140) Drain electrode (150) Gate electrode (160) Plasmonic pattern (170)
