Dispersion Law and the Dependence of the Surface Acoustic Mode Width on the Concentration of Adsorbed Atoms

Section: Solid Matter
Original Author's Text: Ukrainian

Abstract: The dispersion law for elastic surface acoustic waves and the dependence of the surface acoustic mode width on the concentration of adsorbed atoms have been found. The calculations are carried out in the long-wave approximation for the interaction between the adatoms with regard for image forces and the non-local elastic interaction between the adsorbed and matrix atoms.

Key words: deformation potential, adatoms, non-local elastic interaction, image forces, surface acoustic mode width.
