Stranski-Krastanov model grown ZnO thin films

The induced growth of ZnO thin film by crystallized amorpous ZnO as seed crystalline at 80°C has been studied. In order to the better understanding of the growth mechanism of ZnO thin films, as a comparison, we respectively prepared the ZnO thin films at 80°C and 100°C for 30h (both of them). The results of AFM show that the sample surface prepared at 100°C was more rough than that prepared at 80°C. We mainly studied the growth model of ZnO thin films. Through theoretical analysis and modeling ideas, we found that the growth pattern is the Stranski-Krastanov (SK) model, and we also give schematic diagram of the seed crystal induced low temperature self assembly growth of ZnO thin films on c-plane (0001) substrates.
