(a) Resistivity versus temperature, (b) Charge density versus temperature (c) Mobility versus temperature. (d) Mean free path versus temperature. Note the absence of a significant temperature dependence compared with SEG (Fig. 3). Also note that at room temperature, the charge densities and the mobilities are comparable to those of SEG.
