The growth of Ni thin film on the Cu(100) surface at 280 K has been studied by means of thermal-energy helium atom scattering. A near layer-by-layer growth is observed below ~7 ML followed by a multilayer structure at higher coverages. Spot profile analysis shows Ni islands transfer from irregular shape to square with increasing Ni coverage. The mean island separation is measured as a function of coverage. The 0.5 ML Ni/Cu(100) surface turns out to be an ideal prototype, nano-structured surface for future interference measurements.
