| dc.description.abstract | This thesis is based on the study of the electronic properties of Junction between Al and poly[3-(2'-pentyloxy-5'-(1'''-oxoocty)phenyl)thiophene in the form of Al/poly[3-(2'-pentyloxy- 5'-(1'''-oxoocty)phenyl)thiophene]/ITO sandwich structure. The junction between aluminium contacts to poly[3-(2'-pentyloxy-5'-(1'''-oxoocty)phenyl]thiophene films was studied using current-voltage, capacitance-voltage and complex impedance spectroscopy techniques. 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 |
