Özet

Stearic acid incorporating cadmium ions prepared as an Langmuir-Blodgett (LB) thin films were grown onto aluminum coated glass substrate using different thicknesses to investigate the influence of cadmium ions on the electrical properties of the stearic acid. Electrical properties were investigated by measuring C-V and I-V curves at room temperature. The I-V curves show highly non-linear behavior with Schottky conduction mechanism in a high voltage regime for LB film samples. Barrier potential heights were calculated for the stearic acid LB films with and without cadmium ions. It was found that the Schottky barrier is lowered due to the presence of Cd2+ ions.
