Positive core-electron binding energy shifts in small palladium clusters supported on cadmium telluride substrate are shown to arise from the initial-state effects those are more sensitive to cluster size than are the final-state properties and the mean valence band electron binding energy is primarily responsible for the Pd 3d5/2 electron binding energy in lower coverage region (Pd ≲ 1×1015 atoms-cm−2).
