Abstract: | Optical absorption of submonolayer silver films deposited on a fused quartz ATR prism was measured for the spectral range between 1.5 and 6.0 eV. The observed spectra were interpreted well by the model of two-dimensional distribution of rotational ellipsoids applying the classical size effect to ?bound and modifying ?bound from the bulk value better than in the previous paper [Surface Sci. 103(1981)L97], where ?free and ?bound are the dielectric constants of silver contributed from free electrons and bound electrons, respectively. Electron micrographs showed the validity of the geometrical model used for the island films. |
