WebIn this study, we successfully obtained the single crystal of a well-known fused-ring electron acceptor Y6 and realized high ambipolar charge transports in single-crystal organic field-effect transistors (SC-OFETs). These were achieved by growing the single crystal of Y6via a simple solvent evaporation method and then using a “gold trips sticking” technique. WebLow power consumption is of critical importance for organic field effect transistors (OFETs) in next-generation flexible and wearable electronics, wherein the use of high-k dielectric has been proved to be the most promising way. However, high-k dielectrics typically lead to substantial reduction of device p Journal of Materials Chemistry C HOT Papers
