THE EXPERIMENTAL AND CALCULATED OPTICAL PROPERTIES OF NI-AL2O3 COATINGS USING EFFECTIVE MEDIUM THEORIES

摘要

The optical constants of RF planar magnetron sputtered Ni-Al2O3 films are reported for the 0.3-2.5 mu m wavelength range. The data are interpreted in terms of Maxwell-Garnett and Bruggeman effective medium theories. The effect of atomic Ni dispersion in the Al2O3 matrix on the effective medium formalism is discussed.
