Native Graphene Oxides at Graphene Edges

IEEE Transactions on Instrumentation and Measurement, 2012
The boundary between graphene flake and SiO 2 /Si substrate have been probed by scanning capacitance microscopy. Distinctive dot-like protrusions standing on the graphene edges have been observed, and the density of protrusions increases with the increase of graphene layer numbers. Spectroscopic analysis has revealed that the carrier densities at these

Graphene: Graphene's properties

New Scientist, 2012
Just one atom thick, graphene can be folded like plastic film, yet it is stronger than diamond and conducts electricity better than copper or gold.

Superlubric Sliding of Graphene Nanoflakes on Graphene

ACS Nano, 2013
The lubricating properties of graphite and graphene have been intensely studied by sliding a frictional force microscope tip against them to understand the origin of the observed low friction. In contrast, the relative motion of free graphene layers remains poorly understood.
