Abstract | |||||||||||||
| We present an electron spectroscopy study of the development of the electronic structure in the K-doped C60 monolayer on a Ag(1 1 1) surface. We find that the occupation of the lowest unoccupied molecular orbital (LUMO) of the C60 can be varied continuously from 0.75 (undoped) to 6.0 (fully doped). We also find that the density of states at the Fermi level for a doping level corresponding to 3 electrons per C60 is at least a factor of two higher than that found from photoemission on bulk K3C60. This enhanced density of states at the Fermi level might suggest an increased superconducting transition temperature for the monolayer system. | |||||||||||||
