a, b,Colour rendering of Rxx measured in the vicinity of –ns/2 versus Ba and ne at low fields using an r.m.s. excitation current of 5 nA in device A (a) and 4 nA in device B (b). A zero-resistance superconducting state (black) is observed in device B. c, dV/dI versus Idc characteristics at various carrier concentrations ne in the superconducting state in device B at Ba = 0 T using an r.m.s. a.c. excitation Iac = 10 nA.
