摘要: Homogeneous alignment of poly(9,9′-dioctylfluorene) films on rubbed polyimide results in a more than one order magnitude increase time-of-flight hole mobility normal to the direction. We find μ=8.5±1×10−3 cm2/V s at an electric field E=104 V/cm. Hole transport is found be nondispersive, indicating low degree energetic disorder.
