A field-effect transistor structure is used to study the transport properties of the soluble conductive polymer, poly(3-hexylthiophene). We have measured conductance, mobility, and carrier concentration in undoped polymer thin films. The field-effect mobility was found to be 10−5–10−4 cm2/V s at room temperature. The mobility decreases with increased temperature. The change is only partly reversible. Possible transport models are discussed.
