Researchers achieve nanometer resolution measurement of the flow of electrons in graphene

Scientists at the University of Wisconsin-Madison and Japan's National Institute for Materials Science have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results could have applications in developing new, low-resistance materials, where electrical transport would be more efficient. Graphene is a pure electrical conductor, making it an ideal material to study electron flow with very low resistance. Here, the researchers intentionally added impurities at known distances and found that electron flow changes from gas-like to fluid-like as temperatures rise.
