Model of the band structure of the semiconductor film in monoplanar

The expression for the calculation of the energy band structure in monoplanar semiconductor film. In the single-layer structure of the potential energy remains long-range order in the film plane xOy, and has localized in the direction perpendicular to the film plane Oz. This field does not split the energy levels in the conduction band and leads to the splitting of the levels of heavy and light hole valence band. The difference of the potential energy of the axes affects the spin - orbit coupling, this difference is reflected in the coefficient γ.
