摘要：

The differential equation of trap filling with detrapping is solved at the case of tunnel hopping current conduction in insulating layers. The time dependent de current at constant field is shown to give the average values of time constants τ of tunnel hopping transitions, trap distances xt, and trap densities Nt. Increasing the field step by step one obtains a raw feature of the energy distribution of trap density above the Fermi level. Observation of two well separated time constants indicates strong interface region trap filling. The derived method is limited by the change from tunnel hopping to band conduction.
