Stability bottleneck of organic field-effect transistors:from mechanism to solution

Organic field-effect transistors(OFETs)are highly attractive candidates for critical drive components in next-generation flexible and lightweight electronics.In recent years,great progress has been made in the performance and process of OFETs;reports of mobilities greater than 10 cm2 V-1 s-1 alongside large-area fabrications are increasingly common,and numerous proof-ofconcept applications have been successfully demonstrated[1,2].With these advances,OFETs are finding their way from a research hotspot to an attractive technology entering the emerging markets for flexible electronics,such as flexible displays,sensor arrays,radio frequency identification,and wearables.However,the stability issues remain a bottleneck in the progress of OFETs towards a mainstream technology due to intrinsic nature of organic molecular crystals.In future days,understanding the factors that govern the environmental and operational stabilities of OFETs in complicated practical applications,and providing corresponding stability improvement strategies,will be formidable challenges and research priorities.
