Generalization of Child-Langmuir Law for Non-Zero Injection Velocities in a Planar Diode
R. R. Puri, Debabrata Biswas, Raghwendra Kumar
The Child-Langmuir law relates the voltage applied across a planar diode to the saturation value J_CL of current density that can be transmitted through it in case the injection ve…
Power loss in open cavity diodes and a modified Child Langmuir Law
Debabrata Biswas, Raghwendra Kumar, R. R. Puri
Diodes used in most high power devices are inherently open. It is shown that under such circumstances, there is a loss of electromagnetic radiation leading to a lower critical curr…
Absence of saturation for finite injected currents in axially symmetric cavity diode
Debabrata Biswas, Raghwendra Kumar, R. R. Puri
The Child-Langmuir law is investigated numerically using a fully electromagnetic particle-in-cell code for a closed axially symmetric diode. It is found that the average current tr…
