    Notes: Abstract The results of an experimental study of samples of MnxHg1−x Te films grown by liquid-phase epitaxy on a Cd0.96Zn0.04Te substrate are presented. It shows that, as a result of the diffusion of cadmium from the substrate, a CdxMnyHg1−x−y Te film with a variable band-gap layer is formed close to the 〈epitaxial-film〉-substrate interface. The appearance of this variable band gap is revealed by the transport phenomena. The temperature dependence of the band gap E g (T) is determined in a linear approximation on T from the results of a theoretical analysis of the temperature dependences of the free-carrier concentration and mobility. It is shown that averaging the semiempirical dependences for the ternary compounds with the extreme compositions, using the virtual-crystal approximation, can produce large errors when determining E g (T) in a specific semiconductor.

    Influence of elastic stresses on the character of epitaxial crystallization of (Hg, Mn)Te (1997)

    Notes: Abstract Available experimental data on the composition and conditions for crystallization of semiconductor Hg1−z MnzTe solid-state solutions epitaxially grown on Cd(Zn)Te substrates reveal a number of peculiarities, which indicate that the substrate strongly affects the character of crystallization of the solid phase. In this paper we discuss data on liquid-phase epitaxy of Hg1−z MnzTe which suggest the possibility that elastic stresses caused by the mismatch between the crystal lattice parameters of the substrate and the epitaxial layer can influence the composition and conditions for crystallization of these layers. An important tool in our investigation is a thermodynamic analysis of the metastable equilibrium between the stressed solid phase and the supersaturated solution of components.
