A hole mobility for the organic conductor pentacene of μ=35 cm 2/Vs at room temperature increasing to μ=58 cm2/Vs at 225 K was obtained. It was found that these high mobilities resulted from a purification process, in which 6,13-pentacenequinone was removed with the help of vacuum sublimation. The results show that the number of traps was reduced by two orders of magnitude. For electronic transport, the temperature dependence of the mobility was consistent with the band model.
