Characteristics of Pulsed Virtual Cathode Oscillator for Nitrogen Gas
... The Virtual cathode oscillators (vircators) have been studied quite extensively over the last two decades(1,2) In principle, a vircator employs an intense, mostly relativistic electron beam of density greatly exceeding that in a space-charge-limited diode (3,4,5). This leads to the formation of an u ...

P–n diode
This article provides a more detailed explanation of p–n diode behavior than that found in the articles p–n junction or diode.A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer. Semiconductor diodes have multiple uses including rectification of alternating current to direct current, detection of radio signals, emitting light and detecting light.
