The interface consisted of 3.2×1015 atoms cm-2 of gold deposited at room temperature on a crystalline silicon nitride layer, which was previously grown on a Si(111) surface. At room temperature,

Comparison with measurements performed on a Si (111 )-7 ×7 surface helped us in the identification of the band. It is found that this parabolic state is degenerate with surface projected bulk bands of the Si(111) substrate.

The structural properties of the overlayer were investigated by low-energy electron diffraction, the changes induced by adsorption on its electronic properties were studied by valence band and core-level photoemission spectroscopy and inverse photoemission spectroscopy. On all surfaces C60 is chemisorbed and a clear signature for charge transfer
