Paper Abstract

The law of the light refraction and analogues of Fresnel's formulas, obtained from the Maxwell boundary conditions, were used to account for the optical parameters of semiconductors. The calculations, based on our formulas and experimental data on reflectivity at normal incident light of Ge, Si, GaAs, CdS in the region of band-to-band transitions are given. The difficulties which took place earlier in optics of highly absorbing media, disappear in our approach: (1) the angle of refraction is a real value; (2) a real part of dielectric function (epsilon) 1 greater than or equal to 0, because (chi) is less than or equal to n; (3) the index of refraction n is greater than 1.
