GoKawiilResearchers detail anomalous metal and superconducting states in rhombohedral graphene device
Scientists studying a rhombohedral graphene device mapped two distinct electronic phases—an anomalous metal (AM) state and a superconducting (SC) state—by measuring resistance across varying gate voltages, magnetic fields, temperatures and currents. Using multiple voltage probe pairs on a second device, they found the SC and AM regions occupy consistent boundaries in the phase diagram, matching results from an earlier primary device, though the absolute resistance values differed between contact pairs.
