For the possible application of the solution-processed polymer semiconductors to real electronic products, reliable operation of the devices should be guaranteed. In this study, we improved the operation stability of organic field-effect transistors (OFETs) consisting of solution-processed polymer semiconductor/insulator blends. Fluorinated polymer was effectively employed in the polymer semiconductor/insulator blends, which allowed the blend films to have a high energetic barrier to hole trapping from semiconductor nanowires to insulator matrix. Owing to this high energetic barrier at semiconductor/insulator interface, the resulting OFETs exhibited almost hysteresis-free transfer and output characteristics and reliable operation under a sustained gate-bias stress both in N2 and air conditions. |
