Abstract

The energy states at conducting polymer/electrode interfaces have been observed by methods of measuring in the atmosphere. The Fermi level (E_F) of the conducting polymer on several electrode materials was estimated using the Kelvin probe method and the ionization potential (IP) was estimated using atmospheric photoelectron spectroscopy. Based on the observations, the electron transfer at the interfaces was related to the difference of the IP between the conducting polymers and electrode material. The dependence of the E_F of PAT6 on the film thickness differed depending on the electrode materials used, including indium-tin-oxide (ITO), Ag and Al
