Abstract

In this study, the effect of the incorporation of ZnO nanoparticles into poly(3-hexylthiophene) (P3HT) on the electronic properties of P3HT films was examined. Conductivity proportional to ZnO doping was observed. The improvement of conductivity is considered to mainly come from a mobility enhancement. The carrier mobility in P3HT (ZnO-doped P3HT) samples exhibits unexpected temperature dependence, implying the dominance of tunneling in the temperature range of 280-330 K. Hall-effect analysis by using the polaron theory revealed that ZnO doping might lead to an increased spacing between molecules, thus enhancing the carrier mobility.
