Forming semiconductor/dielectric double layers by one-step spin-coating for enhancing the performance of organic field-effect transistors

► Form semiconductor and dielectric layers by one step spin-coating in ambient air. ► Enable high-boiling point solvents to be used in spin-coating semiconductor. ► Simultaneously optimize the dielectric interface and semiconductor crystallization. ► Enhance transistor mobility by 5 times. ► Reduce hysteresis by nearly 90%.
