What information can XPS give?
XPS can provide information about the elemental composition of surfaces, including the chemical state of the elements, binding energy of electron states, thickness of layers near the surface, density of electronic states, and uniformity of elemental composition across the surface and as a function of depth . It can also yield information about the structure, surface termination, built-in electric potentials, and band offsets of films and heterostructures . XPS spectra can be used to identify chemical species at a surface through peak positions and shapes, and the intensities in the spectra can be used to obtain information on the concentration and distribution of chemical species . XPS features can provide insights into the properties and electronic structure of materials, and can be related to underlying chemical and physical phenomena .

XPS can provide information on the elements present in a sample and can also elucidate the chemical state or environment of the sample. It can determine atomic compositions, carbon bonding, presence of electron withdrawing groups, and degree of cross-linking in polymer membranes. It can also provide information on the hydrophobicity and hydrophilicity of materials. | |
