- Abstract
This article reports the investigation on charge transport mechanism in manganese ferrite loaded polyvinyl alcohol (MFO-PVA) nanocomposite film. The basic structure of pure PVA film and the nanocomposite film (MFO-PVA) is studied using the X-ray diffraction technique. With the loading of MFO NPs in the PVA matrix, the conductivity of the composite enhances. The dielectric constant of MFO-PVA film is higher than that of pristine PVA one. The nanocomposite film also exhibits low tangent loss. The current voltage characteristics can be explained using the thermionic emission (TE) and Schottky emission (SE) models considering back-to-back Schottky diode formation. Oxygen-related defect states exist in the polymeric system, which exhibits trapping of the charge carriers.
