Organic field-effect transistors with a low pinch-off voltage and a Controllable threshold voltage

A study was conducted to demonstrate the use of organic field-effect transistors (FET), with a low pinch-off voltage and a controllable threshold voltage for creating integrated circuits (IC). The study demonstrated that several challenges remain in decreasing pinch-off voltage and precision control of the threshold voltage of these organic FETs. It was demonstrated that decreasing pinch-off voltage can widen the saturation region and facilitate the operation of organic FETs in this region, while contributing to cost savings, by enabling the use of lower cost driving electronics, making them suitable for portable applications. It was also demonstrated that threshold voltage is a measure of the amount of charge that needs to be electrostatically induced to switch on the electrical conduction in organic FETs.
