The nanoscale electrical properties of fibrillate poly-3-hexylthiophene are studied using conducting-AFM. The conditions for the prevalence of either local or bulk resistances dominated regime are identified. As local current is space charge limited, an analytical model is derived to determine locally carrier mobility and density.
