a, b k2-weighted Fourier transformed EXAFS spectra of Pd (a) and Cu (b) K-edges; the red circles show the experimental data while the blue curves indicate the fitting results. c Total density of states per PdCu formula, showing the upshift of the B2 bulk with respect to the fcc bulk due to the lower coordination numbers in the first nearest neighbor. d Projected crystal orbital Hamiltonian populations (COHP) between the surface Pd atoms and surface or subsurface Cu atoms of the B2(110) and fcc(111) surfaces.
