New research sheds light on nature of friction in multi-layered graphene

Graphene, which consists of a single layer of carbon atoms, is the poster child of carbon-based 2D nanomaterials. It has many attractive properties that could be exploited in next-generation electronics, optics, catalysis, biomedicine, and many other fields. Recently, many scientists have focused on chemical vapor deposition (CVD) as a cost-efficient technique for producing larger graphene surfaces in lieu of the well-established method of mechanical exfoliation, which can only produce small graphene islands.
