摘要:
Scanning tunneling microscopy (STM) studies of monolayer coverage of C60molecules on a 2H–MoS2(0001) surface reveal electronic features on the molecules that are rather different from those observed on metal and other semiconductor surfaces. The STM current contrast of the adsorbed C60is dominated by that of the underlying crystalline lattice at low bias voltages. The observations can be understood by considering (1) a weak adsorption of C60and (2) an electronic correlation effect between the substrate surface and the molecule. All essential aspects of the experimental STM results are quantitatively reproduced by our calculation. ©1995 American Institute of Physics.
