研究了Ga2O3/In2O3膜反应自组装制备GaN薄膜,再将Ga2O3/In2O3膜在高纯氨气气氛中氨化反应得到GaN薄膜,用X射线衍射(XRD),傅里叶红外吸收(FTIR),扫描电镜(SEM)和透射电镜(TEM)对样品进行结构、形貌的分析。测试结果表明,用此方法得到了六方纤锌矿结构的GaN多晶膜,且900℃时成膜的质量最好。
GaN films were synthesized by ammoniating Ga2O3/In2O3 films deposited on Si(111) suostrates. Tne samples were characterized by X-ray diffraction (XRD), fourier transformed spetra (FTIR), scanning electron microscopy (SEM) ,transmission electron microscopy (TEM). The results show that the films synthesized were hexagonal GaN struture.
