Schottky Barrier Diodes From Electrochemically Generated Polypyrrole-Aluminium Junctions
Published online by Cambridge University Press: 10 February 2011
Abstract
Polypyrrole films were electrogenerated and electrochemically compacted at high cathodic potentials on aluminium. Films removed from the electrode after polarization at -2000 mV show stable bulk conductivities of 10-6 S/cm for months. Planar structures metal/polymer/metal present rectifying properties. The presence of a thin oxidized surface layer having a higher conductivity than that of the bulk polymer can be deduced remaining reduced the polymer mass.
