FAQ: History of Computer Science - You're telling me this is a Computer?

The first working silicon transistor was developed at Bell Labs on January 26, 1954 by Morris Tanenbaum. The first commercial silicon transistor was produced by Texas Instruments in 1954. This was the work of Gordon Teal, an expert in growing crystals of high purity, who had previously worked at Bell Labs

Transistor

Note in particular the Type, which is partially defined by the crystalline substances of which they are composed. Crystals are grown, but not as transistors, per se.

A transistor is made up of three layers. The outer two layers are of the same charge, so likely of the same substance. The inner layer is the opposite of the outer charge. To be this way in nature, it would have to be a different substance.

All in all, transistors are made, and will never occur naturally. Only the substances from which they are manufactured can be found in nature.
