APPLICATION OF THE EMBEDDED ATOM METHOD TO PHONON DISPERSIONS IN COPPER
-
Abstract
The force constants between planes in lattice dynamics have been derived from a new model set by the Embedded Atom Method(EAM), based on tile results from density-functional theory. The semiempirical functions for Cu have been obtained by EAM, and the force constants between planes of Cu are calculated, which produce phonon dispersions in agreement with experiments. -
