The electronic structure and growth mode of C60 molecules deposited on Ag(001) have been studied as a function of deposition parameters and annealing temperature. The measurements show that C60 molecules are chemically bound to the Ag(001) surface even when deposited at 150 K, and the bond properties do not change significantly after annealing up to 670 K. In the resulting ordered C60 overlayer, a mixed contrast of the buckyballs, as seen by scanning tunneling microscopy, is discussed in terms of non-equivalent orientations of the adsorbed molecules.

Abstract
The electronic structure and growth mode of C60 molecules deposited on Ag(001) have been studied as a function of deposition parameters and annealing temperature. The measurements show that C60 molecules are chemically bound to the Ag(001) surface even when deposited at 150 K, and the bond properties do not change significantly after annealing up to 670 K. In the resulting ordered C60 overlayer, a mixed contrast of the buckyballs, as seen by scanning tunneling microscopy, is discussed in terms of non-equivalent orientations of the adsorbed molecules.File in questo prodotto:
