Popis:	Photoelectron diffraction has been used to investigate Au/Cu(001) and Fe/Cu(001). In the case of Au/Cu(001), a structural determination of the 1/2 ML, c(2×2) surface has been performed, indicating that it is a surface alloy with Au and Cu atoms together in the topmost plane and pure Cu(001) underneath. Moreover, the Au/Cu(001) system has been studied as a function of temperature and concentration, allowing a detailed picture of surface alloying and dealloying.
