Notes:
The optical constants, δ=1−n and k, of superthin gold films have been determined from the reflectance data obtained in the soft x-ray region of 60–900 eV. The gold films were prepared to various thicknesses, d=39–270 A(ring), by ion-beam sputtering (IBS) and electron-beam evaporation (EB). A plane-parallel slab model with due consideration for the surface and the interfacial roughness was used to analyze the data by least-squares curve fitting. The optical constants derived for the IBS samples definitely show variations in the vicinity of d=100 A(ring). It is also found that δ of the 201-A(ring)-thick IBS film is smaller by about 7% than that of the 211-A(ring)-thick EB film.
