|Silicon Crystal - 1957
TI number: G00301
This is an experimental crystal grown in about 1957. It was part of the same projects described in G00299.
This silicon crystal was grown on a carbon disk. To get a reasonably uniform cooling rate for the silicon as it formed on the disk., radial slots were cut in the disk. The size and shape of the slots caused the spoke effect in this crystal. Subsequent modifications resulted in solid disks of silicon. The top (seed side) of this crystal was removed to form the flat side with the padded cover.
