IISc Scientists find frictionless graphene flows, defying physics

Scientists at Indian Institute of Science (IISc) have observed electrons in graphene flowing like a nearly frictionless liquid, defying the Wiedemann-Franz law. The phenomenon occurs at a special condition called "Dirac point", where graphene lies between a metal and an insulator. At this stage, electrons no longer act as individual particles but move collectively, exhibiting fluid-like behaviour.
