Abstract

The growth mode and electronic structure of C60 molecules adsorbed on InP(100) were studied by x-ray photoemission spectroscopy and ultraviolet photoemission spectroscopy as a function of coverage and annealing temperature. The C 1s, P 2p, In 4d core levels and the valence band photoemission spectra point to the presence of a localized covalent bond between the C60 molecules and the substrate. No filling of the lowest unoccupied molecular orbit derived bands was observed. The absence of any change in the surface components of the In 4d core level upon C60 adsorption indicates that the chemisorption bond exists between the fullerene molecules and P atoms rather than between C60 molecules and In atoms. This assertion is supported by the simultaneous desorption of both C60 and P upon annealing to 640 K and above.
