ELECTRONIC STRUCTURE OF LOW DIMENSIONAL C_(60)-BASED FILMS

摘要

We comparatively analyze three distinct C_(60)-based superstructures grown on Ag(100), Si(111)-(7x7), and Gc(111)-c(2x8) as to their molecular arrangement and electronic structure. The basic elements characterizing covalent vs. ionic bond of the buckyballs with the substrate are discussed. In particular, the attention is focused onto STM images, photocmission spectra of the C 1s core level and valence band states.
