COMPARING SEGREGATION PROFILES OF Sn AND Sb IN SINGLE AND POLYCRYSTALLINE Cu

ASANTE, J. K. O.; ROOS, W. D. - In: Surface Review and Letters (SRL) 19 (2012) 01, pp. 1250006-1

The kinetics as well as the equilibrium segregation profiles of very low concentrations of Sn (0.14 at.%) and Sb (0.12 at.%) in a polycrystalline Cu sample were measured by Auger electron spectroscopy. These profiles were compared to those from a Cu(100), Sb, Sn ternary single crystal which was...
