The thermodynamic behaviors of charged point defects in the unintentionally-doped ZnO thin films were investigated. The as-grown sample displayed two different types of blue-emission bands: one is at ~2.95 eV from native-donor zinc-interstitial Zni and the other is at ~3.17 eV from native-acceptor zinc-vacancy VZn. In the samples annealed at oxygen ambience, VZn-related emission was dramatically enhanced and Zni-related emission was drastically reduced. The behavior was observed to become more apparent when the annealing temperature was increased. The results can be explained by both the increased generation probability and the lowered formation enthalpy of VZn in oxygen-rich environment, particularly at higher temperature.
