摘要：
Electrical transport properties of PVK (poly N-vinyl carbazole), a polymer exhibiting an intrinsic electroluminescence (EL) in blue region, have been investigated. In particular, resistivity and charge carrier mobility have been assessed by means of I-V measurements and by Field Effect (FET) doping, respectively. Dielectric constant has been also evaluated by means of C-V measurements performed on an ITO/PVK/Al single layer electroluminescent (EL) device. All electrical characterizations, carried Out in different environmental conditions to deeply investigate PVK intrinsic conduction mechanisms, allowed to assess the good quality of spin coated PVK thin films. Electroluminescent measurements performed on ITO/PVK/Al and on ITO/PVK/Alq(3)/Al have been also performed. Finally, charge injection mechanisms from the electrodes to PVK have been investigated also as a function of the temperature. Experimental results have been compared with some well known theoretical models. (c) 2006 Elsevier Ltd. All rights reserved.
