Graphene gains nearly perfect liquid status

Scientists have found the electrons in a layer of carbon atoms can become a strongly interacting swirling soup.

Some things always hold true the amount of time it takes to find your keys, for example, depends on how late you are. Similarly, the rate that electrons collide in a given material is closely linked to its temperature. But graphene - a sheet of carbon that’s only one atom thick doesn’t conform to such rules. Over a wide temperature range, graphene’s electrons should become a strongly interacting swirling soup, scientists report online July 6 in Physical Review Letters.
