Thin-film reactions of Au with Ti, Zr, V, and Nb

Abstract

The thin-film interactions of Au with Ti, Zr, V, and Nb have been investigated between 350C and 700°C with Rutherford backscattering spectroscopy (RBS) and x-ray diffraction (XRD). Initially the most Au-rich phase is formed, except. with V, and it is followed sequentially by the more metal-rich ones in an increasingly layer-by-layer fashion. For Au reactions on Ti and Nb, all the intermetallic phases on the phase diagrams were observed. In the formation of Au4Ti, Au is the dominant moving species.
