초록
The carrier transport mechanism in inorganic/organic hybrid nanocomposites consisting of core/shell type CdSe/ZnS nanoparticles dispersed in a poly (N-vinylcarbazole) (PVK) layer was investigated by using current density-electric field (J-E) measurements. The J-E curves showed that the current density increased with increasing content of CdSe nanoparticles up to 0.2 wt% and that the current density decreased above a 0.5 wt% content of nanoparticles due to the aggregation of the PVK layer. A proposed theoretical model for the carrier transport mechanism is in reasonable agreement with the J-E results.
