Abstract

In this article, a novel annealing technique using alternating magnetic field (AMF) is adopted to improve the electrical characteristics of pentacene film, thereby enhancing the performance of pentacene-based organic thin film transistors (OTFTs). According to the investigation results, the electrical conductivity in the pentacene film could be increased from 0.32 to 1.18 S/cm by annealing the pentacene film using AMF. And also, OTFTs with the pentacene film annealed by AMF exhibited an improved performance compared to the device without annealing. These results suggest that an annealing using AMF can be an effective method to improve the performance of devices based on organic semiconductors.
