Figure 9From: Fabrication of Ni-silicide/Si heterostructured nanowire arrays by glancing angle deposition and solid state reactionSchematic illustrations of the mechanism of two-stage silicidation at the apex of Si nanowire. (a) A schematic illustration of the initial stage of silicidation. (b) A schematic illustration of the second stage silicidation in the Si nanowire with small diameter. (c) A schematic illustration of the second stage silicidation in the Si nanowire with large diameter.Back to article page
