TEMPERATURE-DEPENDENCE OF SURFACE PHONONS OF AL(110)

We study the surface phonons and resonances on the (100), (110), and ( 111) surfaces of aluminum based on a many-atom interatomic potential c onstructed through fitting to a large body of experimental and first-p rinciples configurations. The surface phonons and resonances are calcu lated by use of time-dependent correlation functions from molecular-dy namics simulations. The results are compared with available experiment al data and other first-principles calculations. Our study reveals tha t the temperature effects on the surface modes of Al(110) are importan t for the interpretation of experimental observations.
