Abstract
The band structure of semimagnetic Hg_1-yMn_yTe/Hg_1-xCd_xTe type-III quantum\nwells has been calculated using eight-band kp model in an envelope function\napproach. Details of the band structure calculations are given for the Mn free\ncase (y=0). A mean field approach is used to take the influence of the sp-d\nexchange interaction on the band structure of QW's with low Mn concentrations\ninto account. The calculated Landau level fan diagram and the density of states\nof a Hg_0.98Mn_0.02Te/Hg_0.3Cd_0.7Te QW are in good agreement with recent\nexperimental transport observations. The model can be used to interpret the\nmutual influence of the two-dimensional confinement and the sp-d exchange\ninteraction on the transport properties of Hg_1-yMn_yTe/Hg_1-xCd_xTe QW's.\n
