Abstract:
1. A graphene-layered structure comprising: an ion implantation layer in a silicon carbide thin film; and a graphenized silicon carbide surface layer on the ion implantation layer, wherein the ion implantation layer is in contact with a Si-face surface of the silicon carbide thin film by ion-implanting nitrogen ions into a Si-face surface of the silicon carbide thin film, the ion implantation layer comprises at least one of silicon nitride or silicon carbon nitride, the ion implantation layer has a nitrogen concentration and the nitrogen concentration in the ion implantation layer varies according to a depth of the ion implantation layer, and the graphenized silicon carbide surface layer is on the ion implantation layer by heat treating the silicon carbide thin film with the ion implantation layer therein.
