| Outline of Final Research Achievements |
Intermetallic compounds consisting of group 10-12 elements (NiZn, PdZn, PtZn, PdCd, PtCd), which have d electronic structures similar with copper’s one, were investigated by electron energy-loss spectroscopy based on transmission electron microscopy in order to clarify an origin of the similarity of d electronic structure with copper. Increasing the atomic number of group 10 elements, increasing of interband transition energies attributed to d electrons of the intermetallic compounds was also observed, indicating the d electronic structures are correlated with the atomic number. This is due to overlapping of d electron wave functions of group 10 element. This founding indicates there is a possibility to control the physical functions and/or optical properties of the intermetallic compounds by tuning d electronic structures.
