It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.
