Abstract

The morphology of ALN layers grown by Metalorganic Chemical Vapor Deposition on nano-structured NP-Si(001) substrates coated with SiNx has been studied using atomic force microscopy. The AlN layers grown on the SiNx/NP-Si(100) template demonstrate a surface roughness 3.8 times less than those obtained on NP-Si(100), and are close to the roughness value for the AlN layer grown on a flat Si(111) substrate. It has been proposed a model to explain the differences in the formation of the surface morphology of AlN layers on the NP-Si(100) substrate and the SiNx/NP-Si(100) template.

纳米结构 SiNx/Si(100)模板上生长的氮化铝层表面形态学
摘要 利用原子力显微镜研究了在涂有 SiNx 的纳米结构 NP-Si(001)衬底上通过金属有机化学气相沉积生长的 ALN 层的形貌。在 SiNx/NP-Si(100) 模板上生长的氮化铝层的表面粗糙度是在 NP-Si(100) 上生长的氮化铝层的 3.8 倍,接近在平坦的 Si(111) 基质上生长的氮化铝层的粗糙度值。我们提出了一个模型来解释在 NP-Si(100)衬底和 SiNx/NP-Si(100) 模板上形成的 AlN 层表面形貌的差异。
