AC Impedance Studies of Pyridine Based Polymer Light Emitting Devices
Abstract
We report AC impedance measurement results of pyridine based polymer light emitting devices in the audio frequency region, 10 Hz to 2 MHz. The device structures are metal/polymer/metal layers with polymer layers of order 50 nm. Au, Al and ITO contacts are utilized with sufficient thickness to reduce contact resistance effects. The polymer conductivity is measured to be 4x10-9 inverse ohm-cm. The results are fit to a model which takes into account device geometry. The transport properties will be discussed.
