Researchers have demonstrated superconducting electric currents in the two-dimensional material graphene that bounce between sheet edges without scattering. This first direct observation of the ballistic mirroring of electron waves in a 2d system with supercurrents could lead to the use of graphene-based Josephson junctions in applications such as advanced digital logic circuits, ultrasensitive magnetometers and voltmeters.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/jlnj6GjVnYQ» height=»1″ width=»1″ alt=»»/
