Charge transport and thermoelectric conversion in solution-processed semicrystalline polymer films under electrochemical doping

Abstract

Polymer films are flexible, conductive materials with an expected application to a range of electronic devices, but the complexity of the underlying transport mechanisms inhibit improvements in performance. Here, the authors investigate the transport properties of doped semicrystalline polymer films and determine the role of crystalline domains and boundaries, finding evidence of weak localisation and variable range hopping, which vary with doping level.
