▎ 摘　　要

NOVELTY - The graphene device (200) has graphene structure responsive to continuous in-situ electrical gate-tuning of fermi level. The nanoparticles are placed in relation to graphene structure where each portion of nanoparticles provided with distinct energy bandgap in relation to another portion of nanoparticles. Each portion of the nanoparticles configured to one of activate and deactivate in relation to the distinct energy bandgap and in response to electrical gate-tuning of the fermi level of the graphene structure. USE - Graphene device for filtering color. ADVANTAGE - The graphene structure fermi level increases surpasses and fills first excited state of particular nanoparticle with electrons by drastically reducing the graphene structure photon absorption capability through pauli-blocking effect. The linear dispersion relation of graphene structure allows for the effective tuning of the graphene structure fermi energy level by applying gate bias. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for fabricating graphene device for filtering color; and (2) a method of filtering color by way of graphene device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of graphene structure and nanoparticles are arranged in color array on the graphene structure.
