摘要
Scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) of Dy@C-82 and Dy@C-60 adsorbed on Si(111)-(7x7) surface have been measured at room temperature. The Dy@C-82 molecules in the first layer are randomly adsorbed on Si(111)-(7x7) surface, and the motion of the molecules freezes even at room temperature. No second layer islands are observed before the completion of the first layer. The band gap for Dy@C-82 molecule in the first layer is estimated to be 0.1 eV by STS. The STM image reveals that Dy@C-60 molecule is nearly spherical.
