Description
In this study, the optical and electrical behaviour of polyaniline was studied through Ultraviolet Visible Spectroscopy (UV-Vis) and Current-Voltage (I-V) measurements. The Current-voltage (I-V) measurements showed that a semiconducting diode was successfully formed between polyaniline and silver metal at 1,5M HCl doping. The saturation current Is and ideality factor η were found to be 1,82x10-10 A and 2.0 respectively. From these values, a negative Schottky barrier height was determined to be -1,741 eV. Overall, results obtained in the study present a simple, inexpensive and potentially scalable method for fabricating Schottky diodes suitable for use in radiation sensor elements
