Electronic properties of polyamide–PPy/metal junction and electrical conductivity of a typical sample at low temperatures

Electronic properties of junctions fabricated by polyamide–polypyrrole composite films polymerized with adjusted doping concentration and various metal contacts (In, Al, Au and Ag) were investigated. For the junctions giving good rectification I0, n and φb were specified. Conductivity of polyamide–polypyrrole composite polymer was obtained as a function of temperature in the 70–320 K range and was found to obey the VRH model. In addition the Mott parameters were evaluated.
