(Color online) Typical XRD θ−2θ (a) and the corresponding RSM (b) data of the Zn0.95Cu0.05O film. “S” and “F” stand for substrates and film, respectively.
(Color online) Resistivity (ρ) versus temperature T (a) and T−1/4 (b) curves measured on the studied samples. Solid straight lines in (b) are theoretical fittings according to the Mott VRH model.
(Color online) MR data measured on pure ZnO (a), Zn0.95Cu0.05O (b), and Zn0.95Co0.05O (c) samples with the applied field perpendicular to the film plane. Solid lines are the theoretical fitting results as discussed in the main text. (d) Fitting parameter b in Eq. (3) versus the inverse temperature. The linear lines are a guide to the eyes.
The resistivity , electron concentration , mobility , mean distance between donor , and calculated kFl of the studied samples. All are 5 K data.
