Core level broadening at the surfaces of disordered systems

The “disorder broadening” of core level binding energies in disordered metallic alloys is considered. The origin and magnitude of the effect in bulk alloys is discussed, with particular reference to an intuitive charge model that emphasizes the underlying physics. The model is also used to simulate...

Description
Summary:The “disorder broadening” of core level binding energies in disordered metallic alloys is considered. The origin and magnitude of the effect in bulk alloys is discussed, with particular reference to an intuitive charge model that emphasizes the underlying physics. The model is also used to simulate the core level photoelectron spectra derived from the surface region of various disordered systems.
