Electronic structure of silver (100)

The electronic structure of silver (100) is calculated using the self-consistent local-orbital method. The work function is found to be 4.2 eV. A large density of surface states is obtained, comparable to that found for Ni(100), and larger than we found for Pd(100). →k_∥-selected densities of states (DOS) are given for →k_∥ along the Γ-X̄[110] and Γ-M̄[100] directions. A strong variation with →k_∥ is found. Results for states which are even with respect to mirror-plane reflection are very different from those for states which are odd. Peaks in →k_∥-selected DOS which are due to surface-state bands are identified.
