PACS numbers: 71.15.Dx, 71.15.Mb, 71.15.Pd, 71.18.+y, 71.20.Nr, 71.55.Gs, 81.65.Rv

The valence-electrons density distributions and the electronic energy spectra for the epitaxial Si/CdTe/CdHg1?Te (???0.2)/CdTe and Si/CdTe/CdHg1?Te (???0.2)/ZnS heterostructures are calculated by the methods of the density functional theory and the pseudopotential construction from the first principles. Reduction of the electron-charge density within the CdTe (or ZnS) layers covering the CdHg1?Te film (an insulating effect) is observed. The presence of the potential barriers on the interface of the CdTe/CdHg1?Te (???0.2) or ZnS/CdHg1?Te (???0.2) layers is revealed.
