Germanium superdiode | diyAudio

Germanium Power Devices (run by "Oliver Germanium") made some monster Germanium power rectifiers, possibly as an alternative to Schottky devices. There was a sort of kerfluffle somewhere between the late 70's and early 80's re the reliability of Schottky rectifiers. It was, for hte most part, an application problem rather than a device problem ...

How to Build a Germanium Diode Circuit

» Germanium Diodes - American Microsemi

Germanium Diodes. Early semiconductor developments used germanium as the commercial, semiconductor material. 1) However, due to its ease of processing and more stable temperature characteristics, silicon eventually became the semiconductor of choice. And as a consequence of that, most early germanium semiconductors were replaced with silicon.

Crystal Radio Diode - Peter Vis

A diode is used to demodulate an amplitude modulated (AM) signal. It is a semiconductor material, which behaves as a rectifier. The earliest diodes used germanium as the semiconductor material because a germanium junction can conduct even when the voltage falls as low as 0.2 V.
