A novel SPICE model is proposed for simulating the electrical characteristics of alternating-current thin-film electroluminescent (ACTFEL) devices. The model consists of two capacitors, representing the top and bottom insulators of the ACTFEL device, connected to a Fowler-Nordheim diode shunted by a resistor, which account for conduction and leakage, respectively, in the ACTFEL phosphor layer. A software interface is developed so that the user may conveniently input the two adjustable model parameters (trap barrier height and phosphor shunt resistance) as well as five parameters corresponding to the physical structure of the ACTFEL device (electron effective mass, device area, insulator capacitance, phosphor thickness, and phosphor dielectric constant). Excellent agreement is obtained between measured and simulated electrical characteristics for evaporated ZnS:Mn ACTFEL devices.
