| 摘 要： | 研究了Si纳米线表面Ni薄膜生长工艺。采用热蒸发法以SiO为起始原料制备自组生长的Si纳米线,再以5%(体积分数)HF剔除Si纳米线表面硅氧化合物,采用氩离子磁控溅射的方法在Si纳米线表面溅射一定厚度的无定形Ni颗粒,此后对镀Ni的Si纳米线进行完整晶体结构的退火处理。应用高分辨透射电镜(HRTEM)等结构表征工具分析了Si纳米线表面Ni薄膜的形成过程,HRTEM结果表明,在350℃左右退火得到的Si纳米线表面能形成连续的、结构完整的Ni薄膜;退火温度低于300℃时,表面溅射的Ni结晶效果较差;退火温度在800℃时,表面Ni薄膜发生团聚,形成了分立的纳米颗粒。

| Abstract: | The process of nickel film growth on the silicon nanowires was studied.The self-assembled Si nanowires were synthesized by thermal decomposition of silicon monoxide and their outer silica shells were etched by 5% HF solution.Amorphous nickel nanoparticles were deposited on the surface of etched Si nanowires using argon ion sputtering.After that,the nickel plated Si nanowires were annealed at different temperatures to perfect their structures and the high-resolution transmission electron microscopy(HRTEM)was... |
