In this paper the dependence of the band structure and the electron scattering mechanisms on the molar fraction x are studied in Hg1-xFexSe. The crossover from the zero-gap band to the open band-gap configuration at x ≈ 0.08 is predicted. We explain the drop of the electron mobility for x > 0.002 by the alloy scattering mechanism.
