We extend the adiabatic bond charge model, originally developed for group IVsemiconductors and III-V compounds, to study phonons in more ionic II-VIcompounds with a zincblende structure. Phonon spectra, density of states andspecific heats are calculated for six II-VI compounds and compared with bothexperimental data and the results of other models. We show that the 6-parameterbond charge model gives a good description of the lattice dynamics of thesematerials. We also discuss trends in the parameters with respect to theionicity and metallicity of these compounds.Comment: 16 pages of RevTex with 3 figures submitted as a uuencode compressed  tar fil
