Abstract

The electronic structure of two C60 monolayers deposited on Ag(111) and (100) substrates was investigated. Angle-resolved photoemission was used for the purpose of analysis. It was found that the Fermi surface symmetry, the bandwidth and the curvature of the dispersion are different. It was shown that the orientations of the C60 molecules on two substrates are the main structural differences between the two monolayers.
