Isothermal relaxation current in a dielectric with partially blocking contacts

The continuity and Poisson's equations are solved numerically for a dielectric with partially blocking electrodes in the nonsteady case. The distribution of the mobile-charge-carrier concentration and the electric field strength inside the dielectric is obtained at various times after the potential source is switched on. The time dependence of the isothermal current and the emf of high-voltage polarization of the dielectric with a single type of mobile charge carriers at different values of the contact current is calculated.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 12–16, September, 1985.
