Distribution of Trapped Electrons at Interface States in ACTFEL Devices
Abstract
The distribution of trapped electrons at interface states in alternating-current thin-film electroluminescent (ACTFEL) devices is assessed using a new field-stimulated charge measurement technique in which the polarization charge transient is measured experimentally and curve fit using a model for the dynamic emission of electrons from interface states. The trapped electron distribution is relatively small at low energy but rises abruptly at approximately 0.6-0.8 eV below the conduction band minimum for an ACTFEL device with SiON insulators....
