摘要

Schottky barriers of the type Au/polypyrrole/Al (or In) were made in sand- wichconfiguration. The conductivity ofpolypyrrole was tuned to be on the order of 10~(-3) ohm~(-1)cm~(-1) by its electrodeposition from a novel ambient temperature ternary eutectic melt consisting of acetamide, urea, and ammonium nitrate. The rectification charac-teristics were obtained from the currept-voltage and capacitance-voltage measure-ments at room temperature. The analysis of data using thermionic emission theory gave improved values for the junction parameters of ideality factor, reverse saturation current, rectification ratio, and barrier potential when compared to the previously reported values for this polymer. Between Al and fu metals used Ior the junction formation, the diode formed with Al metal is found to show better performance. The energy gap and work function orpolypyrrole were also estimated.
