摘要：

The formation of Cu/Al2O3 interfaces at room temperature on aluminium polycristalline samples oxidized in different ways has been studied by XPS. We have compared the growth of copper on samples oxidized by O2, H2O and air respectively. In all the analysed systems an initial oxidation of copper to Cu(I) and a good dispersion of the deposited metal is observed, followed by copper clusters formation. The sample oxidized in air shows a better dispersion of the metal and needs a larger amount of copper to reach the bulk copper spectra.
