... which form silicon sulfides by the reaction with silicon, can also be used to assist the growth of SiNWs. In principle, all of silicon compounds, such as silicon sulfide shown in this paper and silicon ... nanowires. This suggests that the nanowires were composed of silicon and silicon oxide as sheath. Actually, some SiNWs could be oxidized to be silicon oxide nanowires because o...
