Abstract
We investigate the mobility of poly(3-hexylthiophene) (P3HT) over a carrier-density range from 1015 to 1020cm-3. Hole-only diodes were used for densities below 1016cm-3 and field-effect transistors were used for carrier densities higher than 1018cm-3. To fill the gap, intermediate densities were probed using chemically doped Schottky diodes and transistors. Combining of the mobilities in doped and undoped devices experimentally establishes the full relation of the mobility over the whole carrier-density range. © 2012 WILEY-VCH Verlag GmbH & Co.
