Abstract
A study of steady-state one-carrier space-charge limited currents in solids containing double-level centers is presented. Using the regional approximation method, asymptotic current-voltage characteristics are derived, as an example, for the case where the thermal equilibrium fermi-level is situated in the lower half of the gap between both defect levels. The results for other energy level schemes are presented. Some considerations related to the information content and to a meaningful interpretation of one-carrier SCLC experiments are given.
