    Abstract

    The vertical mobility of a polymer film prepared on a textured substrate is enhanced from 10-5 cm2/Vs to 10-3 cm 2/Vs by a slow drying process which is unattainable in planar substrate. Highly ordered structure is observed for polymer film treated with high-boiling-point solvent and slow solvent annealing. The enhanced vertical mobility enables the polymer space-charge-limited transistor (SCLT) capable of outputting current density as high as 100 mA/cm2 while maintaining good current gain and on-off ratio. Such vertical transistor is able to drive high-power devices or mechanical actuator in large-area and flexible array.
