Scientists from the Weizmann Institute of Science in Israel used a new material, the thickness of an atom and an innovative new imaging system to show how electrons can “flow” like water. Although scientists have been speculating about this behavior for years, now they have succeeded to visualize it for the first time. To make electrons flow like water, scientists used a more advanced conductor i.e graphene, which is a one-atom-thick sheet of carbon, and which can be made exceptionally clean. This curious new behavior for electrons has significant implications for future electronic devices, including low-power devices in which the hydrodynamic flow lowers the electrical resistance.
