Abstract
The surface composition of evaporated Au(98%)–In(2%) alloy films has been investigated by Auger electron spectroscopy. Sputter etching showed the surface concentration to be markedly different from the bulk concentration. The In concentration on a freshly sputter‐etched surface increases with time and reaches an equilibrium value of [inverted lazy s] 15 at.%, at room temperature. This In‐enriched surface is believed to have the thermodynamically stable composition.Keywords
