Biopolymer-based gate dielectric for organic field effect transistors

Abstract

Organic field effect transistors (O-FETs) are of considerable interest for the development of flexible displays and a variety of other macro-electronic applications. We investigated a DNA-based biopolymer material as a gate dielectric for fabricating O-FET backplanes using the organic semiconductor material Pentacene having small geometry devices and improved performance characteristics required for high resolution displays. The results to date continue to show the potential of this approach for low-cost O-FET backplanes for the next generation flexible displays and other macro-electronic applications.
