High-Energy Resolution Core Level Photoelectron Spectroscopy and Diffraction: Powerful Tools to Probe Physical and Chemical Properties of Solid Surfaces

摘要: Since the seventies, core level spectroscopy has played a key role in elucidating geometric and electronic structure of solid surfaces. Due to their high localization, electrons are extremely sensitive chemical state local environment, for this reason can be used identification configurations. The energy resolution now attainable with technique (below 100 meV) reduced data acquisition time (down few ms per spectrum) opened possibility probe physical properties large variety low-dimensional systems shed light on complex processes taking place characterization mono- bi-metallic materials, investigation atomic molecular interactions surfaces recent findings epitaxial graphene outline potential photoelectron diffraction as precious tools determining nanoscale electronic, geometrical properties.
