Abstract :
In this letter, the effect of the interface on the electrical characteristics of a rectifier based on an organic diode with pentacene as the electroactive layer is studied. It was found that the on/off ratio had a strong correlation with the interface effect (i.e., the bottom electrode material). The rectification ratio was improved to 2 ?? 106 at 5 V by modifying the bottom electrode with copper tetracyanoquinodimethane. The ac rectification frequency exceeded 13.56 MHz, which is a main requirement for an organic radio-frequency identification application.
