Shubnikov-de Haas oscillations in Cdsub(v)Hgsub(1-v)Se

Abstract Oscillations of the magnetoresistivity in Cd v Hg 1− v Se for v = 0.05; 0.075; 0.10 and 0.19 are reported. From the temperaturedependence of the amplitudes of the oscillations, the effective mass of electrons was determined. The effective mass is dependent on concentration. In order to find the energy band gap, E 0 , and the matrix element, P , the k · p method, including interaction with higher bands and finite Δ, was used. It was foundthat the dependence of E 0 on composition at 4.2 K is linear for v < 0.2.
