Direct Visualization of the Nanoscale Morphology of Conducting Polythiophene Monolayers Studied by Electrostatic Force Microscopy

The relation between electronic properties and morphology of conducting polymers has been a central issue since the very beginning of the field. The present paper provides the first direct visualization of highly conducting domains extending over hundreds of nanometers (see cover) in a conductive polythiophene thin film fabricated by the Langmuir–Schaefer technique and studied by electrostatic force microscopy (principle shown in Figure).
