Abstract

The authors present results of measurements of electron concentration and mobility in mixed crystals of Hg1-xZnxSe (0<or=x<or=0.07) doped with resonant Fe donors (0<or=nFe<or=5e1019 cm-3) from liquid helium to room temperature. The data indicate that the presence of Fe considerably improves the electrical properties of the material. The analysis of the mobility in terms of the scattering from ionized centres (with possible spatial correlation of impurity charges taken into account) and alloy scattering leads to an agreement between the measured data and the calculated values.
