- Analysis of Surface Phonon Propagation in Continuum Mechanics
抄録
It is known that crystal structures near the surface are different from those in bulk. In the present paper, the boundary condition taking into consideration of surface density and surface stresses is used for examining the velocity of the surface wave against wave number. The dispersion of the surface wave in an isotropic material is first investigated, and it is shown that the wave velocity decreases with decreasing the wavelength in the case where the surface density and the surface stresses are taken into account. The dispersion properties of surface wave in anisotropic materials, in particular, Ni(001) and W(110) are next investigated, and the dispersion relationship obtained by a continuum approach is compared to the experimental results of surface phonon. The theoretical results considering the surface density and the surface stresses are almost agreed with the experimental ones. In this analysis, the surface density plays an important role for the explanation of behavior of surface phonon against the wave number.
