|Keywords:||Electric fields;Ionization;Light emitting diodes;Films||Issue Date:||2004||Publisher:||American Institute of Physics||Source:||Applied physics letters, 2004, Volume 85, Issue 17, Pages 3890-3892||Abstract:||The carrier transport of carefully purified regioregular poly(3-hexylthiophene) films has been studied using time-of-flight photocurrent measurements. We find balanced ambipolar transport with a room-temperature mobility for holes of 3×10−4 cm2 V−1 s−1 and for electrons of 1.5×10−4 cm2 V−1 s−1 at electric fields ⩾105 V∕cm. The transport is relatively field independent and weakly temperature dependent, pointing to a high degree of chemical regioregularity and purity. These factors make poly(3-hexylthiophene) attractive for use in a range of electronic applications||URI:||http://ktisis.cut.ac.cy/handle/10488/7713||ISSN:||0003-6951 (print)
