Dynamic behavior of submonolayer films of alkali metals on the Cu (110) surface
This work is devoted to a theoretical study of the structural and vibrational characteristics of a two-dimensional film of an alkali metal (Li, Na, K) deposited on an unreconstructed and reconstructed Cu (110) surface. Calculations were made of the equilibrium atomic configuration, polarization vectors of localized vibrational modes, and the local density of vibrational states for different degrees of adsorption of an alkali metal. All calculations were performed using interatomic potentials obtained using the embedded atom method. The obtained numerical values of the structural parameters, frequency and polarization of localized modes are in agreement with the available experimental data.
