Abstract

The surface composition of a series of Nb_xTa_1-x(110) alloys (x = 0, 0.25, 0.5, 0.75, or 1), prepared by electron beam zone melting, has been studied by low-energy ion scattering (LEIS). LEIS shows the enrichment of tantalum at the surface of all alloys. After exposure to oxygen, linear relationships between the oxygen and both the niobium and tantalum signals demonstrate that matrix effects do not influence LEIS signals for these systems. The maximum oxygen coverages of the different alloys are determined by calibration against the Ni(100)-O c(2 X 2) surface.
