Ion distribution preferences in ternary crystals ZnxCd1−xTe, Zn1−xHgxTe and Cd1−xHgxTe
Similar ternary semiconductors are sometimes associated with widely different structures characterized by different site occupation preferences. We have used far-infrared (FIR) spectra to determine the site oc...

Effect of band inversion on the phonon spectra of the Hg1-x ZnxTe alloys
The narrow-gap II-VI and IV-VI alloys are convenient objects for studying the electron-phonon interaction. However, the concentration of free carriers in the IV-VI alloys is rather high (∼1018 cm−3), which compli...
