Germanium Point Contact Transistor
TI number: G00018

Represents the first commercial transistor designed and produced by TI. The germanium was processed by TI. Type numbers were TI101 & TI102.

Points are phosphor bronze and beryllium copper. Sufficiently pure germanium was purchased, mostly from Eagle-Pitcher. It was then refined by a float zone process at TI. Material of the desired resistivity was then used to grow single crystals for the transistors.

Related material in collection: G00002, 3, G00015, 16, 17.
