▎ 摘　　要

NOVELTY - Graphene structure (100) comprises at least one graphene layer (104) including two different dielectric materials. USE - The graphene structure is useful for ultra-sensitive microphotonic devices with mu V inputs. ADVANTAGE - The graphene structure has lower microwave driving voltages, a smaller graphene length, wider microwave frequency range, and reasonable pump amplitudes. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of model graphene structural design. Graphene structure (100) Total length (102) At least one graphene layer (104) Distance (106)
