Surface phonons on Ag (110): A study by means of analytic embedded-atom method
Ag（110）表面声子谱的分析型EAM模型计算

The surface phonons on Ag(110)are studied in the present paper by means of the lattice dynamics and an analytic embedded atom method(EAM). The phonon frequencies and disperse curves with surface relaxation are in good agreement with the data obtained by the helium atom scattering experiments. The polarization and localization of surface vibration are in accord with the two dimensional symmetry in the surface. The S 2 and S 3 surface modes along direction are predicted, which are in agreement with the helium atom scattering experiments.
