Surface electronic structure of fullerides: effects of correlation, electron-phonon coupling, and polymerization

The phenomenology of C60 both as isolated molecule and in condensed phases is reviewed. C60 compounds (fullerides) display a wide range of electronic ground states ranging from magnetic insulators to superconductors. The fundamental properties and interactions (electron correlation, electron-phonon coupling, crystal fields, polymerization, intermolecular screening) which are responsible for the behaviour of these salts are discussed extensively, with an emphasis on the issues which remain open and which will be addressed in this thesis.
