Semiconducting polymers are interesting materials for the use in organic electronics. We investigated the field effect mobility of regio-regular and regio-random poly(3-hexyl thiophene), in dependence of temperature and charge carrier concentration. Our data will be discussed in view of recently published models for charge carrier mobility in disordered organic materials, based on hopping transport of charge carriers in a gaussian density of states distribution.
