Electromagnetic power loss in open coaxial diodes and the Langmuir–Blodgett law

Abstract

The space charge limited current in coaxial diodes with electromagnetic power loss is studied. The Langmuir–Blodgett law is expressed in terms of the electromagnetic power loss and the applied voltage. Particle-in-cell simulations of photodiode-like situations and high power diodes confirm the relation between the applied voltage, diode voltage, and electromagnetic power loss.
