Abstract

This study reports the electronic properties of a family of 3,6-dioxythienothiophene copolymer thin films (referred to as DOTTs) as a function of F4TCNQ doping level. We find that DOTTs have unusually low Seebeck coefficients and that the dependence on carrier concentration could not be accurately explained with present transport models. Furthermore, electrical conductivities were measured as a function of temperature, and some polymer/dopant systems demonstrated unusually low activation energies. The Mott polaron model transport parameters were further evaluated to quantify the effects of carrier concentration. Overall, this work discusses the electronic properties of DOTTs and provides guidance for designing polymer chemistries.
