摘要
The patchy cathode is modeled as a distribution of highly emitting areas in a low emission background. The central limit theorem is used to reduce the distribution to a single gaussian spot. The current-voltage equation is then derived for emission from the gaussian spot and is found to be of a shape which fits well with measured characteristics. Detailed application is made to several diodes using tungsten matrix and rhenium coated tungsten matrix cathodes.
