First-principles Analysis of Photo-current in Graphene PN Junctions
First-principles Analysis Photo-current Graphene PN Junctions
2012/2/29
We report a first principles investigation of photocurrent generation by graphene PN junctions. The junctions are formed by either chemically doping with nitrogen and boron atoms, or by controlling ga...
