Abstract :
Copper doped armchair graphene nanoribbons are investigated using density functional theory. Coinage metal, Cu is doped at one edge as a substitutional dopant and transport properties are investigated and compared with pristine ones. The current-voltage characteristics are enhanced due to the Cu-doping with negative resistance being observed at higher biases. In the transmission spectrum, a typical step like behavior has been observed in pristine AGNR whereas the T.S is greatly enhanced at the Fermi level in Cu-doped AGNR.
