| Sumario: | In the present work we study the basic laws of component distribution distribution on
the epitaxial layer geometry of Hg Mn Te, Hg Cd Te and Hg Cd Mn Te using the micro-X-ray-structural method and the optic method. A curve of standardization was constructed, using the energy band from the experiment to determine the concentration of
cadmium and manganese. Analyzing the absorption spectra structure it was determined that in
the absence of external magnetic field the energy spectra of the charge carriers of the
Hg Mn Te and Hg Cd Mn Te semimagnetic materials and of Hg Cd Te nonmagnetic
material with the same energy gap have the same form. The theoretical calculations of absorbtion spectra were realized within the Kane model with its non-parabolic perturbations specific
for indium antimonide as the narrow-gap semiconductor. |
