| 内容記述 | For continuous thin Ru films and Ru island films consisting of Ru particles smaller than about 320A in diameter, optical absorption has been measured in the photon energy range of 0.5-6.5 eV. Absorption, found below about 1 eV and at about 2, 3, 3.6, and 4.5-5 eV for the continuous thin films, shifted to higher energies and became weaker with decreasing particle size. This change is accompanied by lattice contraction and is similar to the lattice-contraction-induced change in interband absorption of hcp Co. Thus, the absorption is interband absorption as for hcp Co, and is due to transitions from d states into empty states above the Fermi level. The absorption at about 2, 3, and 3.6 eV shifted almost equally (0.2-0.3 eV) and disappeared at almost the same time below about 70A in diameter, indicating that d states are close to each other. The absorption at about 4.5?5 eV was still well defined at about 25A in diameter. Cu, Ni, and Pd particles have also shown such well-defined interband absorption. Thus, as for Cu, Ni, and Pd, d states are presumably in flat or parallel bands. | |||||||||||
