Abstract: A method has been proposed for constructing the two-dimensional pseudopotential describing the electronic structure of the Cu(110) surface. This method can also be applied to construct the corresponding pseudopotentials for the (110) surface of a number of other face-centered cubic metals, such as Ag, Au, Al, Pd, and Pt. The electronic structure obtained can be used for fast calculations of single-particle and collective electron excitations both on the pure Cu(110) surface and on the surface covered with adatoms or ultrathin films of other metals.
