【 摘 要 】

Versatile methods were employed to investigate the chemical reactivity of hydrogenterminated surface of silicon nanowires. The experimental results showed that coupling reaction took place when silicon nanowires reacted with 2,2,2-trifluoroethyl acrylate, and reductive deposition reaction occurred in the presence of inorganic salt such as HgCl2, and also co-reduction reaction took place in a solution containing both AuCl3 and PdCl2. The possible reaction mechanisms were studied and this study would be expected to favour the homogeneity, selectivity, reproducibility, and stability of SiNW devices or sensors.
