摘要
AES、XPS分析和XRD谱结果证明:采用低能双离子束淀积(IBD)技术,在GaSb(001)衬底上共淀积生长了闪锌矿结构c-GaN.X光Φ扫描显示,生长薄膜与衬底晶向匹配关系是c-GaN[110]//GaSb[100].由此可以得到:它们的晶格失配度为4.66%,GaSb是已采用生长c-GaN衬底材料中较好的一种.
Abstract It is verified by means of AES, XPS and XRD that films of zinc blende structure c GaN have been grown on GaSb(001) substrate by Low Dual Ion Beam Deposition (IBD) Technique. The results of X ray Φ scan show that the matched film/substrate growth relationship is c GaN //GaSb . The lattice mismatch is 4 66%. GaSb is a better substrate material used for growing c GaN than others.
