O 2 induced Cu surface segregation in Au-Cu alloys studied by angle resolved XPS and DFT modelling
Surface segregation effects on polycrystalline Au-Cu alloys (Au 0.80Cu 0.20, Au 0.85Cu 0.15 and Au 0.90Cu 0.10) were studied at room temperature by angle resolved XPS (ARXPS) and density functional theory (DFT) before and after exposure to O 2. Au surface enrichment was found as predicted from calcu...
