Although inorganic ambipolar transistors have been around for more than two decades, their organic counterparts, available only in recent years, could be used to make integrated photodetectors, electro-optical circuits and full-colour and monochromatic image sensor arrays. Traditionally, ambipolar organic field-effect transistors (OFETs) were developed as electronic switches. But recently, OFETs with additional functionalities have also made their debut — the most notable examples being the light-emitting (LE-OFETs) and light-sensing (LS-OFETs) transistors.
