INSITU INVESTIGATIONS OF THE CONDUCTION MECHANISMS IN LOW-DIMENSIONAL ORGANIC SEMICONDUCTORS AND METALS

We characterize the electronic structure of polypyrrole films and (2,5-DMe-Dicyanoquinonediimine)2Ag, Rb single crystals using a combination of electrochemical preparation and electron-spectroscopical techniques (XPS, UPS, HREELS). These studies allow to characterize the electronic structure, to conclude on the particular conductivity mechanisms for controlled order and structures, and to determine the strength of both, the electron-phonon and the electron-electron interactions.
