Scientists reviewed the latest developments in research on photoactive organic field-effect transistors; devices that incorporate organic semiconductors, amplify weak electronic signals, and either emit or receive light. Organic field-effect transistors (OFETs) were developed to produce low-cost, large-area electronics, such as printable and or flexible electronic devices.


The researchers reported much progress has been made in the development of light-emitting organic field effect transistors (LE-OFETs) since they first appeared in 2003. Research in this area has resulted in advancement of manufacturing novel organic photonics applications using cost-effective approaches.


Researchers said the light emission efficiency and brightness of the transistors will soon improve. Further research may lead to production of new display technologies. LEOFETs are also expected to fully compatible with well-established electronic technologies. This may allow further development of optical communication systems and optoelectronic systems, such as those using laser technologies.


LE-OFETs are being used to develop flexible, transparent computer screens. These screens are purported to provide faster response times, better efficiency, and no need for backlighting. The reserachers also have very low energy needs. Light-receiving organic field-effect transistors, on the other hand, are much less developed than their light-emitting siblings.
