Abstract
The lattices motion equation and Born-Huang equation was established with the framework of modified random-element-isodisplacement (MREI) model, and the relationship of dielectric constants of lattice vibration and FT-IR reflectivity spectra in ternary mixed crystals ZnS1-xSex with the changes of composition x are discussed. The two-mode behavior of long-wave length optical phonon was studied, and the relation of TO-phonon frequency and LO-phonon frequency with composition was obtained.
