The results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.
