Abstract

The features of the isothermal discharge of a dielectric containing single-energy traps after a voltage pulse V0(tu) is applied to the specimen, during which charge carriers (electrons) are injected into the volume of the dielectric (monopolar injection), are considered. The initial stage of the discharge is analyzed at instants comparable with the time of flight of free carriers, and also the discharge under conditions of self-consistent variation of the internal field and the volume charge in the dielectric when the external field is switched off and only the “pulling” field e1 s e0 remains. Analytical expressions are obtained which describe the change in the total current, the displacement current, and the conductivity, and also the variation of the total charge with time, by means of which one can estimate experimentally the main parameters of the material: Et, σv,μ, nt.
