| dc.description.abstract | This thesis is based on the study of the electronic properties of PEOPT in the form of AI/PEOPTIITO sandwich structure. An interface between aluminum contacts to PEOPT films were studied using complex impedance spectroscopy and current-voltage characteristic measurements. The current density-voltage curve is asymmetric and non-ohmic and shows Schottky barrier type rectification. The complex impedance spectra are semi-circles that show the existence of a region depleted of mobile charge carriers. An equivalent circuit consisting of one parallel RC circuit is envisaged as a model of the interface | en_US |
