N-DOPING METHOD OF GRAPHENE

摘要

PURPOSE: A method for n-doping graphene is provided to easily dope large sized graphene by using an amine compound or a material with reducibility as n-type dopant. CONSTITUTION: A method for n-doping graphene includes the following: graphene(20) is grown on a substrate(10) by reacting reaction gas containing carbon sources and heat on the substrate; the graphene is n-doped based on n-type dopant containing doping liquid(30) or n-type dopant containing vapor; and the n-type doping liquid is dropped on the graphene to form a liquid doped layer on the graphene.
