Abstract
Organic field-effect transistors were fabricated using an electrochemical route. The dielectric oxide was grown by anodization of a Ti:Si alloy, while 3,4-polyethylenedioxythiophene has been employed as a semiconducting polymer. OutputI-Vcharacteristics showed a transistor effect dependent on dielectric thickness. Fitting between I-V measurements and theoretical simulations in the triode region confirmed the presence of a conduction path through the polymer which degrades the electrical characteristics of the devices.
