Observation of room-temperature single-electron tunneling (SET) in a conjugated polymer is reported. It is observed that conjugated polymers in the high doping level are composed of some ordered (metallic) and disordered (semiconducting) regions. This property has been exploited in conducting polypyrrole nanotubes to form some ordered regions separated by disordered regions. The nonlinear current–voltage and positive temperature coefficient of resistance in the high-temperature limit confirm the desired morphology of the tubes. Isolated metallic islands, which are necessary to observe SET have been formed disrupting the nanotube in the semiconducting (disordered) portions by applying a voltage pulse.
