Abstract :
A temporal model based on the Howard, Sahni, and Alt model (1982) that 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 is developed. A fast and efficient numerical procedure that calculates the steady-state hysteretic state of a ZnS:Mn thin-film device is developed for the above model. Graphs of device current and luminance that result from the above model are given
