Abstract
Inorganic nanoparticles Fe2O3 3–5 nm in diameter were assembled on the surface of polymer microspheres and then encapsulated in the polymer to form a trilayer composite structure. The capacitance–voltage (C–V) curve of the composite microsphere monolayer shows the presence of a plateau. The electron transportation process in the special structure was investigated combining with the energy band model. The results show that Fe2O3 layer acts as a charge trap between polymer layers which are regarded as potential barriers.
