Comment on ``First-principles theory of the evolution of vibrational properties with long-range order in GaInP2''
Abstract
Ozolins and Zunger [Phys. Rev. B 57, R9404 (1998)] performed an ab initio calculation of the optical modes of CuPt ordered GaInP2. We show that their assignment of the phonon modes presents a fundamental incoherence.
