摘要：

Homogeneous alignment of poly(9,9 '-dioctylfluorene) films on rubbed polyimide results in a more than one order of magnitude increase in time-of-flight hole mobility normal to the alignment direction. We find mu = 8.5+/-1 x 10(-3) cm(2)/V s at an electric field of E = 10(4) V/cm. Hole transport is found to be nondispersive, indicating a low degree of energetic disorder.
