Patent ID: 8900538

Claim:
A method of making a semiconductor device, comprising: providing a graphene sheet; creating a plurality of nanoholes in the graphene sheet to form a graphene nanomesh, the graphene nanomesh including a plurality of carbon atoms which are formed adjacent to the plurality of nanoholes; passivating a dangling bond on the plurality of carbon atoms by bonding a passivating element to the plurality of carbon atoms; and doping the passivated graphene nanomesh by bonding a dopant to the passivating element, the dopant comprising one of an electron-donating element for making the graphene nanomesh an n-doped graphene nanomesh, and an electron-accepting element for making the graphene nanomesh a p-doped graphene nanomesh, wherein the dopant comprises a metal atom and the bonding of the dopant to the passivating element comprises a chelation process in which the metal atom is bonded to an atom of the passivating element such that a ring is formed in a hole of the plurality of nanoholes, the ring comprising the atom of the passivating element, the metal atom, and a carbon atom of the plurality of carbon atoms.
