Hybrid heterojunction thin films, based on poly-(3-octylthiophene) (P3OT) polymer and oleic acid (OA)-capped cadmium selenide (CdSe) nanoparticles (NPs) are prepared by a spin-coating method. The structural and morphological properties of the CdSe NPs and of the hybrid thin films are investigated. The results of the dielectric characterization show that conductivity of the hybrid thin films is dependent on frequency and CdSe NP concentration.

The dielectric properties of spinel ferrites were investigated in the frequency range 50 Hz-10 MHz and in the temperature range 300-420 K. Conductance is shown to increase with increasing frequency and temperature.
