Theory of transient currents in dielectrics at a limited level of single injection. II. The case of weak injection

A theory of transient currents in dielectric layers at a limited level of single injection is suggested. A complete analysis (for all stages of the transient process) of three mechanisms of the transient characteristic of a weak injection region is fulfilled. Analytic expressions, describing the time behaviour of the quantities of total current, total charge, space-charge centroid, and electric field strength on the injecting interface are obtained.
