Abstract(in English) | Crystalline structure of ZnO thin films, which were grown on a-plane sapphire substrates through a reaction between dimethylzinc and high-temperature H_2O produced by a Pt-catalyzed H_2-O_2 reaction, was measured. From the thickness dependence of the electrical properties, the electron mobility at room temperature increased from 54 to 189 cm^2V^<-1>s^<-1> with increasing film thickness from 200 nm to 2800 nm. The temperature dependences of the Hall mobility and carrier concentration of ZnO films with thinner than 500 nm and thicker than 500 nm were quite different. The existence of the layer with high-defect density near the film-substrate interface was estimated. In this study, the crystalline structure of the ZnO film with 5μm thickness grown on the a-plane sapphire substrates was observed using cross-sectional transmission electron microscopy (TEM). The dislocation density in the films was also evaluated under two-beam condition. |
