What Happened to Germanium Transistors? The Transistors That Couldn’t Take the Heat

Описание: Before silicon ruled electronics, there was germanium.

It powered the first working transistors, transformed hearing aids, captured the imagination of hobbyists, and helped shrink the radio from a piece of furniture into something small enough to carry.

For a few remarkable years, germanium seemed destined to become the foundation of the electronic future.

Then engineers discovered a weakness hiding inside the material itself — and another semiconductor was waiting to take its place.

This is the story of germanium transistors: the tiny devices that helped launch the transistor age, put radios in American pockets, and then quietly disappeared from the center of electronics.
