Magnetophonon Resonances on Three Phonon Modes in ZNXCDYHG1-X-Yte Epitaxial Layers
Four-component materials Zn x Cd y Hg 1-x-y T e have an important advantage. In a crystal lattice only the cationic part is changed: Hg, Cd and Zn while the anionic part remains unchanged. On the one hand this means that it is possible to obtain better quality crystals and epitaxial films; on the other hand it leads to the interesting phenomenon of the mixture of transverse and longitudinal optical oscillations of each mode:HgTe-like, CdTe-like and ZnTe-like.1,2 The energies of phonons have been presented in Table 1.
