摘要 研究了射频等离子体辅助分子束外延生长GaN晶膜中氮等离子体的发射光谱。用非接触式测量方法———光谱法测定了等离子体特性。讨论了分子束外延生长系统参数的变化与等离子体发光光谱变化之间的联系 。 The emission spectra of nitrogen plasma,used in GaN film growth by RF plasma molecular beam epitaxy (MBE) was studied.Influence of the variations in emission spectra on the growth parameters was discussed.How activated particles in the plasma affect film growth was also tentatively discussed.
