The possibility of using lasers to form semiconductor materials
(cadmium and mercury tellurides) with a predetermined width
of the band gap was explored using mathematical modeling. A one-
dimensional physicomathematical model based on diffusion and heat
conduction equations and transport equations for laser radiation
with temperature- and concentration-dependent coefficients was used.
Self-similar solutions were used in order to obtain certain
qualitative regularities of the processes. In the general case
the corresponding system of partial differential equations was
integrated numerically.
