Lattice dynamics of silver and gold on Krebs's model
Description
Phonon dispersion relations along the principal symmetry directions of gold and silver have been calculated for phonons propagating at room temperature. The calculated curves are compared with the recent experimental findings. Also calculated are the lattice heat capacities of these metals at absolute zero temperature. Computed(theta - T) curves of them show good agreements with experimental results. The effect of various forms of the dielectric screening functions on the calculated phonon spectrum of gold and silver has also been investigated
