The structure and optical properties of Pb1-xMnxSe (х = 0.02—0,04) epitaxial films grown on BaF2
(111) substrates in vacuum 10-4 Pа by the method of molecular beam condensation have been investigated.
Optimum conditions of reception for structurally perfect (W1/2=80—100,,)
epitaxial films of different chemical composition alloyed with gallium (≤ 0.8 аt.%) have been determined.
It is shown that the edge of spectral dependence of the optical absorption factor for investigated films is varied
by change of х and is shifted to short wavelengths which is explained by increase of band-gap width of
Pb1-xMnx
