Schottky Diodes and Thin Films Based on Copolymer : Poly(aniline-co-toluidine)‎

الملخص EN

Poly(aniline-co-o-toluidine) (PANI-co-POT) thin films were deposited on indium tin oxide- (ITO-) coated glass substrates by electrochemical polymerization under cyclic voltammetric conditions from aniline-co-o-toluidine monomer in an aqueous solution of HCl as a supporting electrolyte.

These measurements showed that the optical band gap of the copolymer films is on the order of 2.65 eV.

On the other hand, ITO/PANI-co-POT/Al devices were fabricated by thermal evaporation of Aluminum circular electrodes on the as-deposited PANI-co-POT films.

The Current-Voltage characteristics of these devices are nonlinear.

The diode parameters were calculated from I-V characteristics using the modified Shockley equation.

The C-F characteristics were also measured.
