In this theory-based episode, Derek explores the silicon diode! He covers some of the history of this component, from the thermionic diode to the modern diode we are familiar with today. He touches on the basics of PN junction semiconductor physics, and then he takes some actual measurements on a cheap curve tracer so we can better understand what's happening.
