Abstract :
A temporal model is developed which describes hysteresis, the transient and the steady-state values of the interface state charge, and the trapped bulk charge in an AC thin-film electroluminescent device. A fast and efficient numerical procedure which calculates the steady-state hysteretic state of a ZnS:Mn thin-film device is developed for the model. Graphs of device current and luminance which results from the model are given. The hysteretic luminance-voltage curve calculated from the model matches an actual experimental curve for reasonable values of device parameters.<>
