Pentacene Organic Field-Effect Transistors with Polyimide Gate Dielectric: Fabrication and Performance

This research focuses on the fabrication and characterization of pentacene organic field-effect transistors (OFETs) utilizing a polyimide gate dielectric layer. OFETs, based on organic materials, hold promise for various electronic and optoelectronic applications. The study begins by preparing the pentacene organic semiconductor material. Subsequently, a polymer known as polyimide is employed as the gate dielectric layer. This layer acts as an insulator between the gate and the organic semiconductor, enabling control over electron transport. A thin film deposition technique is then utilized to deposit the pentacene organic semiconductor material onto the polyimide gate dielectric layer. This technique ensures an even and thin film coverage of the organic semiconductor over the dielectric layer. Finally, the performance of the fabricated pentacene OFETs is assessed by analyzing their electrical characteristics, such as current-voltage and output characteristics. In conclusion, this research successfully demonstrates the fabrication of pentacene OFETs using a polyimide gate dielectric layer and evaluates their performance. The findings contribute to the advancement of organic material-based electronic devices.
