New Study Shows Fluid-Like Motion of Electrons in Graphene
Scientists at the National Graphene Institute in Manchester, England conducted a series of experiments on electrons in graphene. They learned that electrons behave differently within the material, and can come together to flow like a liquid.
Be Like Water
In graphene, electrons move in strange ways. Their unusual and fluid-like behavior was observed by scientists at the National Graphene Institute, leading to a new wave of studies related to the physics of conductive materials.
Three experiments were conducted, including one at the University of Manchester, in collaboration with physicists led by Professor Marco Polini and Professor Leonid Levitov. The results of the tests showed how — withing a specific range of temperatures — electrons move and collide so often they eventually flow like a viscous fluid.
This fluid is more conductive than ballistic electrons — electrons that move throughout the material in a scatter-pattern manner. Instead of remaining separate, electrons in this new fluidic state work together without impeding the flow of current, which is how move and provide power to everyday electronics. Typically, the scattering pattern impacts this flow, making a material less conductive. Think of a weakened flickering light.
