The role of impurities on the electronic properties of graphene nanoribbons

A first principles study through Density Functional Theory is implemented to exhibit the role of impurities on the electronic structure properties of graphene nanoribbons. After the optimization of both pristine and doped graphene materials, numerical calculations are performed to elucidate their electronic transport behavior. It is revealed that incorporation of structural defects in the form of impurities, manipulating the electronic characteristics of graphene structures, can give rise to effective functional devices that can be harnessed in various technological applications.
