Polar polymers (polyfluorene copolymers, PFN-PBT) with different polarities are utilized to modify the surface of tantalum pentoxide (Ta 2 O 5 ) insulator in n-channel organic thin-film transistors (OTFTs). A high mobility of 0.55 cm 2 /Vs, high on/off current ratio of 1.7 Â 10 5 , and low threshold
