The substrate dependency analysis of the crystalline characteristic of ZnO films
Abstract: Functional material is the basis of human social development. Semiconductor materials and technology has been one of the most active areas of high-tech research field. ZnO, as a multifunctional semiconductor material, has a very wide range of applications in many areas. In this topic, the seed layer was deposited by radio sputtering on the single crystal materials, and then ZnO-based films were prepared by ultrasonic spray pyrolysis. The comparison analyses of the structure, crystallinity and optical properties of ZnO-based films on the substrate with and without the seed layer were performed by XRD and PL measurements. The substrate dependency of the crystalline quality and physical properties of ZnO films was studied, and the mechanism of the affect of the seed layer on the film growth mode was discussed. This study can provide the reference for the research of high-quality films material. Meanwhile, these research results will promote the application of ZnO thin films.
Key words：Semiconductor films， crystallinity, seed layer, doping
