Figure 4From: Electron transport in a GaPSb filmR xx ( B = 0) as a function of T ranging from 4.2 to 80 K (black curve). The blue solid line denotes the theoretical VRH contribution described by Equation 3 and the red one corresponds to the activation part. Their sum is presented by the green dotted line. The inset shows lnG as a function of T−1/4.Back to article page
