【Abstract】 Using scanning tunneling microscopy, scanning tunneling spectroscopy and theoretical simulations we have studied the local structural and electronic properties of individual metallofullerene molecules, and spatially mapped the energy-resolved metal-cage hybrid states of a single endohedral metallofullerene Dy@C 82 isomer I. The relative position of the Dy atom in the cage and the orientation of the molecule are inferred by comparing the experimental results with theoretical simulations. This combined technique provides promising applications in characterizing and diagnosing nanodevices based on a single molecule.更多还原
