Researchers from the University of Arkansas released a study that has some new insights into how graphene-metal junctions work. Specifically, they show how the graphene-metal interface affect the movement of electrons through two-terminal junctions.
The researchers say that when you form covalent bonds (by attaching the transition metals to graphene) you destroy the unique electronic properties of graphene. The researchers say that their research does not use doped graphene, which is expected in real devices. They found that the electrons at these graphene-metal junctions behave much like a light beam does when it is shone on a crystal -- some of the light scatters and some of it goes through.
