采用直流热阴极等离子体化学气相沉积(DC-PCVD)方法,以三聚氰胺(C3H6N6)的甲醇(CH3OH)饱和溶液为掺杂源,通过改变反应气氛中的Ar浓度,在P型Si(111)基片上沉积了氮掺杂纳米金刚石膜.采用扫描电子显微镜、拉曼光谱仪、X射线衍射仪、霍尔测试系统等分析了不同Ar浓度对氮掺杂金刚石膜生长特性的影响.结果表明:随着Ar浓度的增加,膜的晶粒尺寸逐渐减小,表面变得光滑平整;由拉曼G峰漂移引起的压应力先减小后增大;膜的导电性能变好.且由于C3H6N6的引入,使得在较低的Ar浓度下(H2/Ar流量比为100/100时),即可制得晶粒尺寸在30 ~ 50 nm的高质量的金刚石膜样品,远低于H2/Ar体系的Ar浓度为90%的阈值.
