Abstract
The failure of empirical tight-binding interpolation schemes has given the impression that only the most sophisticated self-consistent calculations can provide accurate details of the electronic structure of noble metal surfaces. It is suggested here that a simple, nonempirical calculation in an atomic orbital basis can also yield a quantitatively useful picture, including the position and dispersion of prominent surface states and surface resonances at Cu(100) and Cu(111).Keywords
