The effects of size on the growth kinetics of nanowires by the vapor-liquid-solid mechanism are presented. The dependences of the growth rate and the activation energy of crystallization on size are given quantitatively. The obtained theoretical results show that the smaller the nanowire radius, the slower the growth rate, and the activation energy of crystallization will increase with decreasing radius of the nanowire. These theoretical predictions are in agreement with the experimental cases.
