Single-crystal graphite appears to be a better contact material for graphene than conventional metals. So say researchers at Columbia University in New York who have found that the contact resistivity of the graphite–graphene interface can be as low as 6.6 Ωμm2. A reduced contact resistance could not only be useful for improving devices made from the carbon sheet but also for fundamental physics studies on the material……
