Superconductivity of Fullerenes and Scanning Tunneling Microscopy of Novel Superconductors.
Abstract
This work examines the electronic structure of new fullerene compounds by the combination of in situ transport measurements as a function of temperature and photoemission spectroscopy. In particular, we have grown thin films of cerium fullerides, Ce(x)C60, 0.5<x<l3, by co-evaporation of multiple molecular beam sources. Resistivity as a function of temperature showed activated transport as a function of temperature at all compositions between 9 and 300 kelvins. Core level photoemission spectroscopy showed weak hybridization of Ce 4f orbitals with the valence band for x<11 and strong hybridization at high cerium concentration. Valence band photoemission spectroscopy shows electronic correlation effects. jg p.1
