Auger electron spectroscopy (AES) and low energy electron diffraction (LEED) were applied to investigate the segregation of aluminum atoms on a Cu-9 at.% Al(1 1 1) surface. We observed that the Al concentration in the top layer ranged between about 9 and 36 at.% after the sample we used was annealed at different temperatures. The phenomenon of Al atoms segregating on the surfaces was explained well by considering the diffusion length of Al atoms in bulk Cu. LEED measurements showed that (root 3 x root 3)R30 degrees structures grew as the concentration of A] atoms increased. The segregation phenomena on surfaces resulted in a stable two-dimensional Cu(67)Al(33) alloy phase in the top layer. (C) 2009 Elsevier B.V. All rights reserved.
