Hole mobility enhancement of MEH-PPV film by heat treatment at Tg

The hole mobility of poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) film was measured using the time-of-flight method. The hole mobility was enhanced 4-fold after annealing at around the glass transition temperature (Tg). Optical, atomic force, and Kelvin force microscopies, a...
