Carrier injection in nonbonding π states of N-doped graphene by an external electric field
作者： Manaho Matsubara , Susumu Okada
关键词:
摘要: Using the density functional theory combined with an effective screening medium method, we studied electronic structure of N-doped graphene under external electric field. The states near Fermi level depend on carrier concentration reflecting their wave function distribution. associated dangling bond shift upward increasing electron concentration, following level. nonbonding π almost retain energy upon hole/electron doping by
