Abstract
The DC circuits containing the Child-Langmuir (CL) diodes as their components are proposed for the first time for studying and calculation. The CL-diodes have a volt-ampere characteristic in the form of the power law with an exponent of 3/2. The devices that should be related to the category of CL-diodes include vacuum thermionic diodes with direct currents limited by the electron beam own space charge, solar cells, semiconductor light-emitting diodes, high-power diodes of direct-acting electron accelerators, etc. Circuits containing several CL-diodes have not been considered before anywhere. Formulas for general perveance with parallel- and series-connected CL-diodes having different perveances are given. Two calculation examples of the general perveance of the circuit containing three and four CL-diodes are presented. The methods and results of this study can be used for calculating the volt-ampere characteristics of, e.g., complex multicomponent circuits of solar cells or light emitting diodes.
