Feibelman d-parameters for crystalline noble metals

Tabulated Feibelman d-parameters obtained from quantum mechanical optical response simulations of a noble metal surfaces having either (100) and (111) crystallographic orientation as described by 1-D pseudopotentials; in each data file, the first column contains the optical frequency in electron volts (eV), while the second and third columns provide the real and imaginary parts of the d-perpendicular parameter, respectively, in nm.
