Using first-principles calculations, effects of intrinsic stacking faults on the work function and surface energy of the (1¯10) surface of face-centered cubic metals were investigated. A simple rule was summarized based upon the calculated results. It was found that the work function of the metals of IA, IIA, IIIA, IIIB, IVB and VIIB groups decreased due to the intrinsic stacking faults, whereas Fe of IVB group was an exception; the work function of the metals of IVA, IB and VIII groups increased whereas Fe and Pt were two exceptions. However, for the concerned 28 metals, the corresponding surface energy of (1¯10) decreased except Mn, Fe, Tc, Ru, Hf, Re and Os. The mechanism for such changes was further discussed.
