Outline of Final Research Achievements

Structure of Sm nano particle was measured by scanning tunneling microscopy (STM). While Sm nano particle less than 0.2nm shows nonmetallic characteristics, the particle greater than 0.3nm shows metallic characteristics in the STS spectrum. For Sm bulk crystal the its d,f electronic states near the Fermi level have empty states, these empty states on the Fermi level is not observed in the nano particle. We have observed the localized electronic states are sensitive to the change of local atomic structures.
