Graphene Becomes Superconductive

Caption

This image shows temperature dependence of electrical resistivity of Ca-intercalated bilayer graphene, measured by the micro four-point-probe method (inset). The resistivity shows a rapid decrease at around 4 K and reaches "zero" at 2 K, showing the emergence of superconductivity.
