dc.description.abstract	We have studied the phonon dispersion and density-of-states on the (110) surface of LI-VT compounds CdTe, ZnTe, and ZnS in their zinc-blende phase by applying the adiabatic bond charge model. The relaxed surface atomic geometry and the corresponding bond charge information is obtained from the application of an ab initio pseudopotential calculation. The origins of various surface phonon modes are discussed and their variation for different compounds are analyzed in terms of the reduced mass and total mass differences. Furthermore, we have related some differences between surface modes on II-VI (110) and III-V (110) in terms of the ionicity factor.
