Abstract

Thin SiO/sub x/ films were deposited using ECR-PECVD. The composition and structure of the samples was determined using Rutherford backscattering and Fourier transform infrared spectroscopy while photoluminescence and ellipsometric measurements were used to characterize the samples optically. AFM measurements confirmed the presence of silicon nanocrystals after annealing the samples. These materials have the potential to he used in a variety of applications, including rare-earth doping, as well as their applicability to optical coatings because of the large achievable range of refractive indices.

ECR-PECVD沉积SiO/ subx /光子学薄膜的组成和光学特性
采用ECR-PECVD沉积SiO/ subx /薄膜。利用卢瑟福后向散射和傅里叶变换红外光谱对样品的组成和结构进行了测定,并利用光致发光和椭偏测量对样品进行了光学表征。原子力显微镜测量证实了样品退火后硅纳米晶体的存在。这些材料有潜力用于各种应用,包括稀土掺杂,以及它们对光学涂层的适用性,因为可实现的折射率范围很大。
