Abstract

In a recent paper(1) a simplified model was proposed and an analysis of electron bombardment induced processes was given. The analysis considered only one type of carriers, neglecting space charge effects. It was shown that the dead voltage in cathodoluminescence and induced conductivity is related to the diffusion length of the induced carriers. The present paper being a continuation of the above, deals with a more elaborate model. An analysis of the ambipolar diffusion of induced carriers will be presented and some space charge effects will also be considered.
