Abstract
We have studied effects of deposition temperature on electrical properties of (ZnO)x(InN)1-x (ZION) films on ZnO templates. With increasing the deposition temperature from RT to 450°C, the electron mobility decreases from 93 cm2/Vs to 70 cm2/Vs and the carrier density increases from 1.8×1019 cm-3 to 3.4×1019 cm-3. Furthermore, we found a correlation between electrical properties and root mean square (RMS) roughness of the films. These results suggest the surface flatness is an important parameter to determine electrical properties of ZION films.
