Determining of the material parameters of Zn_xCd_yHg_(1-x-y)Te by the magnetophonon spectroscopy

摘要

The phonon and electron subsystems were studied in quaternary solid solutions of Zn_xCd_yHg_(1-x-y)Te (ZMCT) by means of Raman scattering and Magnetophonon Resonance. The Raman spectra of several compositions confirm the three-mode behaviour of phonon spectra. The cluster mode has also been observed. Four kinds of LO-phonons (of HgTe-like, CdTe-like and ZnTe-like sublatticies and ZnTe-clusters) 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.
