Phonon densities of states, dielectric constants, the Born effective charges, interatomic force constants of stoichiometric apatites Me₁₀(PO₄)₆X₂, where Me = Ca or Cd and X = F, Cl, Br, OH, were calculated in the framework of DFPT with pseudopotential approach and plane wave basis sets. Phonon densi...
