Abstract
The reflectivity of the compound Ga(1-x)AlxSb has been measured at room temperature for different x, from 0.5 to 1.3 eV. The value of epsilon (o) has been calculated using the refractive index n=(1+ square root R)/(1- square root R). A non-linear composition dependence is reported. A model of calculation of epsilon (o) is proposed taking into account the energies of transitions E0 and E2.Keywords
