The electrical response of ZnS:Mn alternating-current thin-film electroluminescent devices grown by atomic layer epitaxy (ALE) is studied by systematically varying the characteristics of the standard driving waveform. Charge-voltage, capacitance-voltage, and internal charge-phosphor field analysis are used to accomplish electrical analysis. The turn-on voltage, polarization charge, conduction charge, leakage charge, relaxation charge, preclamping interface state density, and steady-state phosphor field are all monitored as a function of the driving waveform for both polarities. The electrical response is found to be asymmetric with respect to the polarity of the applied voltage pulse; this asymmetry is attributed to an asymmetry of the interface state density and to the existence of space charge within the ALE-grown phosphor layer.
