摘要：

C60 molecules adsorbed on the Cu(111)1 x 1 surface have been investigated by the field ion-scanning tunneling microscope (FI-STM). C60 molecules initially segregate to the terrace edges and grow, with increasing coverages, into a monolayer film with the close-packing fcc(111) configuration which results in a 4 x 4 overlayer phase. Highly featured STM images of C60 adsorbate have been observed and interpreted for the first time based on the local density of the states of C60 adsorbed on the surface. Based on various STM images as a function of the bias voltage, four possible C60 adsorption geometries are determined.
