Abstract

A simple integrated circuit design is used to demonstrate the NOR logic and dual input inverter. On a flexible Polyimide substrate, a phototransistor and resistor are both solution-processed and fabricated simultaneously. The high performing logic gates were made possible by integrating a PEDOT: PSS drop-casted resistor with an optimised PTB7-Th p-type organic field-effect transistor (OFET) which has a high mobility of 0.5 cm2 V-1 s-1 and a very low threshold voltage of 2 V. The inverter achieves a gain of 12.5 and a high noise immunity of up to 98 percent. It is shown that the resistive load inverter can work with a single transistor as NOR gate with both light and voltage as input signals.
