Abstract :
We measured temperature dependence of voltage–current characteristics of electrochemically polymerized polypyrrole in micron scale using scanning probe microscope. The morphology and the magnitude of room temperature resistivity, ρRT=0.016 Ω cm, are similar to other electrochemically synthesized polypyrrole. I–V characteristics became non-linear for T<100 K and can be fitted to fluctuation-induced tunneling conduction model.
