Abstract

The devices with a structure of ITO/$Alq_3$/Al were fabricated and their impedance properties were analyzed. It is obtained that an effect of resistance $R_p$ of the device was dominant at the low frequency and the high voltage region, emitting region, and it is ignored at the high frequency region. Capacitance $C_p$ appears intensely in a range of all frequencies of non-emitting region, below turn on voltage.
