WebJan 1, 2015 · Crystal growth is initiated by dipping a silicon seed crystal (which is mounted on a moveable pull rod) into the free surface of the silicon melt. The seed is then slowly withdrawn from the melt, which causes the crystallization of silicon atoms at the melt–crystal interface of the seed by forming a new crystal portion. WebIn crystal pulling, a machine lowers a seed crystal until it just kisses a glob of melt, then gradually moves the burgeoning seed upward, timing its motion to coincide with the crystal's growth rate. Changing the movement rate …
WebThe crystal pulling method dips a seed into a heated container of melted nutrients and synthetic crystals slowly grow from it as it is gradually pulled away from the melt.
