Influence of the hybridization of impurity electron states on the quantum magneto-oscillation phenomena in mercury selenide with iron impurities

Abstract

Experimental study of the concentration dependence of the parameters of the Shubnikov–de Haas and de Haas–van Alphen oscillations in mercury selenide crystals containing iron impurities under conditions where the donor resonance energy level of the impurities falls into the conduction band and hybridization of the electronic states occurs. The observed concentration dependence of the Dingle temperature and g factor of the electrons exhibit minima correlated in position with the maximum of the electronic mobility. It is shown that the observed anomalies can be explained on the basis of a previously developed theory of hybridization effects.
