Abstract

Graphene has been an interesting material for scientists and engineers by virtue of its remarkable properties. It has unique electronic properties with zero bandgap at the Dirac point. The absence of bandgap in graphene limits its application in electronics. The formation of graphene nanoribbons and substitutional doping of graphene are the methods to manipulate the geometric and hence electronic structure of graphene. Starting from the geometric and electronic properties of graphene, this chapter involves a discussion on the geometric and electronic structure of graphene nanoribbons and substitutionally doped graphene systems based on first principles studies.
