Transient space-charge-limited currents in photoconductor-dielectric structures: A comment

The calculation presented in an earlier paper is refined to include closed-form solutions for integrals of the exponential integral that were treated numerically in the original work. This allows us to demonstrate the equivalence of our results to those of Many and Rakavy for the limiting case of direct electrode contact to the photoconductor (no dielectric present). © 1971 The American Physical Society.
