 Abstract: The electron emission accompanying the oxidation of Cs fullerides was investigated in relation to the electronic structure of the CsxC60 surface. No electron emission could be observed during oxidation of solid Cs fullerides, independent of the Cs doping, i.e. independent of the occupation degree of the C60-t1u-derived orbitals. However, the oxidation does result in a very intense electron emission when the CsxC60-heterostructures contain Cs atoms remaining on top of the solid saturated fullerides (x = 6). This emission is almost two orders of magnitude more intense than that observed from the same Cs amount deposited on a metallic substrate. This enhancement of the emission can be attributed to the unique electronic and structural properties of the Cs clusters formed on top of a non-metallic fulleride phase.
