Multimode nature and magnetophonon resonance of quaternary solid solutions of zinc, cadmium, and mercury tellurides

The magnetophonon resonance in a multimode crystal of the solid solution ZnxCdyHg1−x−yTe (x=0.08, y=0.11) was investigated in the temperature interval from 77 to 200 K. To interpret the obtained structure of the magnetophonon resonance spectrum, the phonon modes of three compositions of this solid solution were studied by the Raman scattering method. The results presented confirm the three-mode behavior (excluding cluster modes) of the phonon spectrum of the solid solutions of this class. The complicated structure of the magnetophonon resonance bands is interpreted on the basis of the values obtained for the phonon frequencies. The characteristic features of electron transport in such a lattice are shown.
