Abstract

In ternary tellurides two reststrahlen bands are associated with vibration of the two types of near neighbor atoms. A very simple model allows for evaluation of the corresponding effective charges and force constants for each type of dipole. The results show clearly the destabilization of the HgTe bond when Cd is substituted for Hg and the strengthening of this bond when Zn is substituted for Hg. The force constants behavior in CdZnTe appears of the same type as in CdHgTe but is more complex.
