Low-voltage polymer-dielectric-based organic field-effect transistors and applications

Organic field-effect transistors (OFETs) are of great significance in next-generation optoelectronics and have made remarkable advances during the last decade. For the commercialization of OFETs, power consumption is one of the main issues needed to be addressed. To this end, OFETs with low-voltage operation are constructed, and several strategies have been successively developed, which have attracted intensive attention for researchers to achieve this goal. In this review, we summarized the recent progress of various approaches for realizing low-voltage OFETs, including adopting high-k dielectrics, ultra-thin dielectric, electrolyte dielectric, and interface engineering. Besides, the potential applications of low-voltage OFETs in organic electronics are introduced. Finally, we give a brief outlook of this area for the future direction.
