(a) R-T transitions and (b) R-H transitions for as-grown and etched sample B. (c) The linear resistance Rlin at I → 0 [deduced from the I–V curves in Fig. 4(d)] as a function of temperature for etched sample B. (d) I–V curves measured at magnetic field μ0H = 0 T for etched sample B. (e) Scaling of the I–V curves in (d).
