研究目的
Investigating the thermal oxidation effects on the physical properties of CuO2 thin films for optoelectronic applications.
研究成果
The study demonstrated that annealing temperature significantly affects the structural, morphological, and optical properties of CuO2 thin films. Higher annealing temperatures led to increased transparency and changes in the energy band gap. The films showed potential for optoelectronic applications due to their favorable optical properties.
研究不足
The study is limited to the effects of thermal oxidation on CuO2 thin films prepared by RF sputtering. The range of annealing temperatures and the specific conditions of the sputtering process may not cover all possible variations in film properties.
