via HACKADAY: History Of The Diode

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic emission and semiconductor diodes. So let’s dive in. VACUUM TUBES/THERMIONIC DIODES Our first accidental discovery was of thermionic […]
