Figures

Image of FIG. 1.
FIG. 1.

Real and imaginary parts of the dielectric function vs energy for alloys. The spectra that correspond to the ternary end compounds are plotted with thicker lines. The spectra are shifted in the value specified on the left of each curve.

FIG. 2.

Real and imaginary parts of the dielectric function vs energy for and samples. Closed squares and open circles represent the experimental data while the solid lines correspond to the theoretical fits of these data.

Image of FIG. 3.
FIG. 3.

Compositional dependence of the and interband transitions in alloys. Closed squares, triangles and open circles represent our data and data taken from Ref. 7, respectively.

Image of FIG. 4.
FIG. 4.

Experimental (closed squares and open circles) and theoretically calculated using the modified Adachi model and the SA algorithm (solid lines) spectral dependence of the absorption coefficient , and normal-incidence reflectivity for and samples.

Image of FIG. 5.
FIG. 5.

Experimental (closed squares and open circles) and theoretically calculated using the modified Adachi model and the SA algorithm (solid lines) spectral dependence of the real refraction index and extinction coefficient for and samples.

Image of FIG. 6.
FIG. 6.

Real refraction index vs photon energy for alloys. The solid line shows the calculated result after Eq. (5). Closed squares represent the experimental data.
