The quantum-size effects are shown to play a crucial role in defining pattern formation of metal island on surface.@footnote 1@ The energy in elongated needle-like growth is found to oscillate with the width of the needle, clearly demonstrating the existence of preferred needle widths. The energy of the square or rectangular islands varies periodically with the side length, predicting stability variations of the islands with different sizes.
