ABSTRACT:
A rotationally-vibrated unidirectional solidification crystal growth system comprises a furnace, a crucible, a rotational-vibration device including a mounting holder, a motor and a vibrating apparatus. The furnace contains a high temperature portion, a thermal isolation portion and a low temperature portion. The crucible connected to the rotational-vibration device within the furnace has a seed well down to a crystal growth arena. The crystal is grown as the ambient temperature profile moving from high to low, which can be achieved through a relative movement between the furnace and the crucible. That is either the furnace or the crucible is undergoing a top-down movement. The rotational-vibration device offers the crucible the required rotation and angular vibration, with a vibrating frequency no less than 0.2 Hz.
