Exploration of Organic Transistors for Circuit and Light Sensing Applications

Organic transistors fabricated with high-k P(VDF-TrFE) as gate dielectric and TIPS-pentacene:PS blend as active layer were investigated for light sensing and circuitry applications. These devices operated at low voltage of -5V with high Ion/Ioff of 103. These devices were explored for light sensing, and it was found that these devices exhibited higher sensitivity to blue light illumination compared to the other counterparts, red and green. In addition, circuit applicability of these devices was demonstrated through resistive load inverters.
