“…In this manuscript we present far-infrared reflection spectra of Hg 1-x Zn x Te crystals over the composition range 0.1 ≤ x ≤ 1 and, in agreement with preliminary investigations [1], a two-mode phonon behaviour is observed. The frequencies of the transverse (TO) and longitudinal (LO) optical modes are determined by the Kramers-Kronig transformations, that from peaks in Im(ε) and Im(-1/ε) give frequencies of TO and LO phonons.…”

The complex dielectric function «ðEÞ ¼ « 1 ðEÞ þ i« 2 ðEÞ ð 10:1Þcan be used to describe the optical properties of the medium at all photon energiesThe complex refractive index n Ã (E) can also be given bywhere n(E) is the ordinary (real) refractive index and k(E) is the extinction coefficient. From Equation (10.2), we obtain Properties of Semiconductor Alloys: Group-IV, III-V and II-VI Semiconductors Sadao Adachi

Interatomic force constants are deduced from a fit of infrared reflectivity data of HgCdTe (MCT) and HgZnTe (MZT) mixed crystals using a basic unit model for the description of vibrational modes of low wave vector. This allows, for the first time, a direct comparison of bond strengths between MCT and MZT. The obtained results are consistent with a slight decrease in bond strength when Cd is substituted for Hg in MCT and an increase when Zn replaces Hg in MZT. These results are visualized through the bulk modulus variations with composition in both mixed crystals and are compared to known results on their thermal properties.
