Title: Effect of the luminescent layer thickness on the conduction mechanism in light-emitting devices
Keywords: Electroluminescence; Emission; Interfaces; Layers; Organic; Polymers

Abstract: Light-emitting structures were prepared with new polymer material based on ethylhexyloxy-phenyles used as emissive layer. Ohmic and Schottky contacts, made from golden and indium-tin oxide, were deposited as thin film anodes for investigation of the conduction mechanism at the electrode interfaces and in the bulk of devices. The influence of the polymer film thickness over the electrical characteristics was investigated. For golden anode, space charge formation and bulk limited conduction mechanism was found. For indium-tin oxide anode, complex behavior of the structures was found, which suggests mixed mode of injection limited conduction and electric field dependence of the charges mobility according to the space charge limited conduction model.
