The name similarity is a bit coincidental. The crystal in a crystal radio was a rectifier (most often, these days, a germanium diode, which is, a type of crystal). The crystal in a crystal ...

Seymour solved one of the outstanding problems of his day: how to fabricate a germanium crystal rectifier capable of withstanding high back-voltages (>100V). This was the major contribution of ...

The logic is actually done by crystal rectifiers, but the tubes do inversion. To make an and/or/invert gate requires a single triode or half of a 6J6A. A D flip flop requires three tubes or two ...

1940s radar relied on a semiconductor crystal, or "rectifier." Radar worked by sending out a radio wave and analyzing the reflected wave after it bounced off any objects in the air. The rectifier ...
