Semiconductor nanowires, such as InAs, InP, β-Ga2O3, and GaP are synthesized by annealing semiconductor wafers covered with Au film at an appropriate temperature in the region of 550°–650°C in a N2 atmosphere. The composition of the resulting semiconductor nanowires is determined by both the substrate and the chemical conditions of growth. High-resolution transmission electron microscopy and selected area electron diffraction reveal high degrees of crystallization of the as-grown nanowires. The characteristics of the annealing method for synthesis of semiconductor nanowires are discussed.
