▎ 摘　　要

NOVELTY - The graphene waveguide has silicon oxide layer (2) that is formed on the silicon substrate (3). The silicon oxide layer is provided with the graphite dilute layer (1). The graphite dilute layer is provided with Y-shaped graphite dilute inner zone and Y-shaped graphene outer zone. The chemical potential of Y-shaped graphene outer zone is 0.4eV. USE - Graphene waveguide. ADVANTAGE - The chemical potential of the graphene can be realized. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene waveguide.
