摘要: 采用热丝化学气相沉积方法,优化金刚石薄膜制备工艺。通过改变甲烷浓度成功制备出厚度均匀的多层金刚石薄膜,实现了多种调制周期的金刚石薄膜制备,调制周期最小至100 nm。通过拉曼光谱和X射线衍射方法对单层以及多层金刚石薄膜进行应力分析,发现单层结构中,微米金刚石薄膜应力最大,随着金刚石晶粒尺寸的减小,薄膜应力减小;多层金刚石薄膜结构中,微米层与纳米层均匀交替生长,有效地降低了薄膜应力,有利于提高金刚石薄膜在应用中的稳定性。

Abstract: The hot filament chemical vapor deposition method was employed to optimize the preparation process of diamond films. Multilayer diamond films with uniform thickness were successfully prepared by altering their methane concentration, making it possible to prepare diamond films in various modulation cycles. The modulation cycle was as low as 100 nm .A stress analysis of single and multilayer diamond films was conducted using Raman spectroscopy and X-ray diffraction methods. It was found that the stress onmicrodiamond films in the single-layer structure was the highest, and would decrease as the size of diamond grains increased. In the multilayer structure of diamond films, the microlayer and nanolayers alternately grow in a uniform manner, which effectively reduces the stress on the films and improves their stability in applications.

Key words: hot filament chemical vapor deposition, multilayer structure, diamond film, stress analysis
