Abstract

Abstract : Organic ambipolar transistor arrays for chemical sensors are prepared on a flexible plastic substrate with a bottom‐gate bottom‐contact configuration to minimize the damage to the organic semiconductors, for the first time, using a photolithographically patternable polymer semiconductor. Well‐balanced ambipolar charge transport is achieved by introducing graphene electrodes because of the reduced contact resistance and energetic barrier for electron transport.
