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.
众所周知,晶格失配和热应力失配是GaN异质外延中位错产生的主要原因;为此,我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试,其中尝试了侧向外延生长技术,得到了低位错密度(小于10〓/cm〓)、高质量的GaN外延层;尝试多低温缓冲层法,发现材料中的应力特性与生长系统和生长条件有关,材料中的应力与位错密度按相反方向变化;首次尝试高低温联合缓冲层法,材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大,从而导致随后高温GaN外延膜中位错密度降低,并且能够有效地抑制黄光峰。
