Abstract
We report a systematic study of the Hall mobility and the carrier concentration of a conjugated polymer [poly(4,4′-dipentoxy-2,2′bithiophene)] as a function of the electrochemical doping level, over a wide range of the carrier concentration (from ∼1015 to ∼1019 cm−3). Very high values were obtained for the carrier mobility (from 102 to 10−1 cm2 V−1 s−1), when compared with those reported in the literature for organic materials. Furthermore, an inverse relationship between mobility and carrier concentration was found.Keywords
