Structura spectrelor de reflexie ale antimonidului de galiu dopat cu fier

Abstract

In present paper it is analyzed the reflection spectra structure of nondoped gallium antimonide and gallium antimonide doped with iron in different concentrations at T=300K temperature. The investigated samples were obtained by zonal fusing modified method. The reflection spectra has a complex structure. In reflection spectra structure registered for gallium antimonide doped with iron, are distinguished a set of particularities about modification of the optic transition from region of Van Hove critical point. Using Kramers – Kroning model were calculated the optical constants specific to gallium antimonide energetic spectrum.
