Empirical band calculations of the optical properties ofd-band metals. II.Ag1−xCdxalloys

Abstract

Empirical band structures and the imaginary part ${\epsilon }_2$ of the dielectric constant have been calculated for the alloys ${\mathrm{Ag}}_{1-x}{\mathrm{Cd}}_x$ ($x=0.1, 0.2,\mathrm{and} 0.3$) using a combined interpolation scheme. The parameters were derived from those of pure Ag by applying a sinking-$s$-band and shrinking-$s$, $p$-gap model. The ${\epsilon }_2$ results reproduce the intensity and shape of the experimental data of Green and Muldawer.
