... silicon atoms. The continuous absorption induces the supersat-uration of the formed liquid alloy with silicon atoms, which leads tonucleation and growth of a SiNW [19]. Therefore, the diameter ... of SiNWs. The reaction temperature is usually decided with the consideration of the catalyst type. According to the binary phase diagram of a metal and Si, the temperature for SiNW formation must ... oxidized with an oxide shell of 1–3nmaccording to the Eq. (2) (Fig. 3A).3.2. Sulfide-assisted growth of SiNWsIf the growth with a metal catalyst can cause contamination, the synthesis without...
