Nature of physical problem

Determination of phonon dispersion and phonon eigenvectors for zincblende structure and diamond structure materials.

Method of solution

Deformation-Dipole model and Rigid ion model calculation of dynamical matrices (refs. [1-5}) 'xl K. Kunc, 0. Hoim Nielsen / Zincblende structure compounds Restrictions on the complexity Zincblende structure (and diamond structure) crystals. Some compounds are not yet well described by the above models. Typical running time 0.5 s per phonon (CDC), 0.25 (IBM).
