TLDR
In this paper, X-ray photoemission measurements were performed on Au deposited on a Bi(2212) single crystal after progressively sputtering it with Ar ions, and the results revealed no elemental diffusion at the interface and an absence of Au interaction with the crystal at room temperature.Abstract:
X-ray photoemission measurements were performed on Au deposited on a Bi(2212) single crystal after progressively sputtering it with Ar ions. This was to see whether changes such as diffusion of Au, segregation of a particular element or clustering effects take place at the interface. Spectra of different core levels reveal no elemental diffusion at the interface and an absence of Au interaction with the crystal at room temperature.read more

TL;DR: In this paper, the core-level results show that Rb strongly reacts with the Bi and O states, while the Cu and Sr states are left unchanged, and that the Bi-O plane forms the surface layer.
