Class Information
Number: 117/83
Name: Single-crystal, oriented-crystal, and epitaxy growth processes; non-coating apparatus therefor > Processes of growth from liquid or supercritical state > Havin growth from molten state (e.g., solution melt) > Growth confined by a solid member other than seed or product (e.g., bridgman-stockbarger method) > Having bottom-up crystallization (e.g., vfg, vgf)
Description: Subject matter in which crystal growth initiates at the lowest point in the melt and progresses up; e.g., vertical freeze gradient (VFG).
