T dependence of R using Arrhenius mapping.
R (in log scale) vs. 1/T at different B′s ranging from 0.5 to 12 T. The solid lines represent data acquired by two-terminal measurements, while data obtained from I-V scans are shown as markers. The dashed lines joining the markers are guides to the eye. The dashed black line demonstrates how an activated behavior should appear in an Arrhenius plot.
