摘要
Using reactive radio-frequency magnetron sputtering, epitaxial growth of ZnO film was observed on Si (001) substrate at different temperatures ranging from room temperature to 750 degrees C. The epitaxial relationship was determined to be ZnO(001)parallel to Si(001) in the direction normal to the surface of the films with a deviated angle less than 3 degrees and ZnO[100]parallel to Si[110] or ZnO[310]parallel to Si[110] in the plan view. Based on (2x1) reconstruction of Si (001), a heteroepitaxial model was suggested to discuss the influence of Si (001) substrate on the growth and morphology of ZnO films at different temperatures.
