Abstract

The electrodeposited polypyrrole (PPY) film over ITO coated glass substrate has been prepared and its current voltage response using Schottky emission theory has been analyzed. The electrodeposition of PPY has ben carried out by electrochemical polymerization of 0.2 M pyrrole monomer and cycling the potential between -0.2V to 0.8 V at a scan rate of 20mV/s using KCl as supporting electrolyte. The formation of polymer has been confirmed by X-ray diffraction and FTIR measurements whereas the surface morphology has been observed using scanning electron microscope. The band gap of PPY film has been calculated using UV visible spectroscopy and found to be 2.4 eV. In addition, the current-voltage response of deposited film was also recorded to evaluate its electronic attributes such as barrier height (empty set(B)) and constant factor (beta). The results revealed the empty set(B) and beta values of 0.314 eV and 1.72x10(-4), respectively. These films may have potential applications in electronic and optoelectronic sensing devices.
