Higher Energy X-ray Photoelectron Spectroscopy

There is growing interest and activity in photoelectron spectroscopy using X-ray sources with energies higher than Al Kα. With this collection, Surface Science Spectra (SSS) aims to provide a database of reference spectra for materials using these higher energy X-rays. Higher energy photoelectrons have greater sampling depth than traditional XPS, and the measurement of larger overlayer thicknesses and buried interfaces becomes possible. As such, this collection includes XPS data collected using higher-energy XPS instruments or synchrotron HAXPES facilities for elements and simple compounds of known stoichiometry as well as spectra from layered materials. The collection will be a valuable database for the community on the practical information depth, and will serve as a reference to the growing community of higher-energy XPS users.
