Lattice dynamics of transition metals in real space

摘要: Abstract The effective ion-ion interaction is written as the sum of s-s, d-d attractive and overlap interactions. free electron part pair potential obtained in second-order perturbation theory using a two-parameter Heine-Abarenkov model modified Lindhard dielectric function has been suggested by Hafner Heine. d states different ions effect s-d hybridization Wills Harrison are considered. temperature dependence included an approxmate manner. It then used to calculate phonon spectra number transition metals FCC phase. agreement between predicted observed values found be reasonably good for all metals. binding energy elastic constants these also calculated.
