Micro-pulling-down


The micro-pulling-down method is a crystal growth technique based on continuous transport of the melted substance through micro-channel made in a crucible bottom. Continuous solidification of the melt is progressed on a liquid/solid interface positioned under the crucible. In a steady state, both the melt and the crystal are pulled-down with a constant velocity.
Many different types of crystal are grown by this technique, including Y3Al5O12, Si, Si-Ge, LiNbO3,
α-Al2O3, Y2O3, Sc2O3,
LiF, CaF2, BaF2, etc.

Crystal growth routine

Standard routine procedure used in the growth of most of μ-PD crystals is well developed. The general stages of the growths include:
