本文研究了用射频等离子体辅助分子束外延技术在γ-LiAlO 2上生长GaN和(In,Ga)N/GaN多量子威尔斯阱。GaN层表现出良好的光学和电学性能,而结构质量受到劣质衬底形态的显著影响。(In,Ga)N/GaN多量子阱结构在室温下具有较强的紫光和蓝光光致发光。
We study the growth of GaN and (In,Ga)N/GaN multiple quantum wells on γ-LiAlO2 by rf plasma-assisted molecular beam epitaxy. The GaN layers exhibit promising optical and electrical properties, whereas the structural quality is significantly influenced by inferior substrate morphology. The (In,Ga)N/GaN multiple quantum well structures show intense room-temperature photoluminescence in the violet and blue spectral range.
