H4P1: VACUUM DIODE

Although vacuum tubes are no longer commonly used in computer or consumer electronics, they still have a substantial niche in high-end audio, high-power radio transmitters, particle accelerators, and microwave ovens.

A vacuum diode, the simplest vacuum tube, is an interesting two-terminal device.

A vacuum diode's voltage-current characteristic is closely approximated by the Childs-Langmuir Law, with one parameter called the perveance:
