Temperature dependence of the power factor for the ZnO obtained by different methods.Figure S3. Temperature dependence of the weighted mobility for the ZnO obtained by different methods. The weighted mobility was calculated in the framework of the effective mass model [1].Figure S4. XRD patterns of the Al-doped ZnO samples with nominal composition Zn1–xAlxO (x = 0.02, 0.04, 0.06). On the right: An enlarged section in a 2θ range from 35° to 45° where ZnAl2O4 spinel phase, indicated by a solid black triangle (▼), has the most intensive reflections. Due to the experimental conditions, reflections caused by Kβ radiation were also observed in the presented diffractograms, with two of the most intense reflections indicated with black circles (●). Positions of Bragg’s reflections for the main ZnO phase are indicated by ticks on the top part of the figure.Figure S5.
