The Sb induced crystallization of physics vapor deposit amorphous silicon can be observed on sapphire substrates after annealing at 770 K. The influence of annealing time on crystallization of amorphous Si by Sb is investigated. We find the crystallization of amorphous silicon can occur at 770 K, even for a very short annealing time.
