Abstract

In this paper, we have prepared Zn – ZnOx from Zn metallic by thermal oxidation under air ambient with various oxidation durations. The root mean square roughness values are quadratic dependent with oxidation duration and the maximum value of root mean square is 65 nm. The current-voltage characteristic of Al contacts on samples show resistivity increases with oxidation durations. It may due to the formation of ZnO on Zn layer. These results are in good agreement with the observed trend in Raman spectra. The intensity of E2 (high) was increasing with oxidation duration. Thus, the formation from Zn to ZnOx becomes dominant. The absorption band at 535 cm-1 indicates the presence of Zn - O compound.
