Abstract

The electronic properties of graphene nanoribbons (GNRs) with heteroatom (boron or nitrogen) substitutional doping at different sites are investigated by performing first-principles calculations based on density functional theory. The calculated results show that boron substitutional doping changes the conducting characteristics of GNRs to half-metallic. In contrast, nitrogen substitutional doping results in retention of the half-metallic characteristics of GNRs. It is predicted that the theoretical results may be valuable to the design of GNR-based spintronics devices.
