ingotlt.jpg (59251 bytes)
Designed, built, and installed an industrial silicon ingot lifetime tester capable of measuring lifetime on large crystalline ingots or multicrystalline blocks of silicon.  Measurements can be made on as-cut surfaces without special sample preparation, using a unique probe head and contacting system. The instrument is especially useful for monitoring the quality of ingots before expending resources on wafering and PV cell fabrication.

webdislo.jpg (167331 bytes) Improved a ribbon melt growth process by implementing high-yield seeding procedures, eliminating undesired motion of shallow melts, thermally decoupling melt replenishment from ribbon growth, and characterizing dislocation and lattice distortion phenomena via X-ray topography.
emcconso.jpg (42772 bytes) Demonstrated a "containerless" silicon feedstock particulate consolidation system based on our cold-crucible electromagnetic semicontinuous casting process
