Determining of the material parameters of ZnxCdyHg1-x-yTe by magnetophonon spectroscopy

Abstract

The phonon and electron subsystems were studied in quaternary solid solutions of ZnxCdyHg1-x-yTe by means of Raman scattering and Magnetophonon Resonance. The Raman spectra of several compositions confirm the three-mode behavior of phonon spectra. The cluster mode has also been observed. Four kinds of LO-phonons participate in the electron-phonon interaction. Four types of one-phonon Magnetophonon Resonances and two types of Magnetophonon Resonances on the difference of phonon frequencies have been observed.
