PES stands for photoelectron spectroscopy, which in the case of our lab is performed on negative ions. Here's how negative ion photoelectron spectroscopy works: a laser is used to detach the extra electron from a mass-selected beam of negative ions, and the kinetic energies of the electrons are measured in a hemispherical energy analyzer.

Resulting from a critical evaluation of the published literature, the database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. In this work, we show that circular dichroism angle-resolved photoelectron spectroscopy provides a powerful tool that can resolve the topological and quantum-geometrical character in momentum space. In particular, we investigate how to map out the signatures of the momentum-resolved Berry curvature in two-dimensional materials by exploiting its intimate connection to the orbital polarization. X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing a material’s surface chemistry. XPS can measure elemental composition as well as the chemical and electronic state of the atoms within a material. 2019-02-01 · X-ray photoelectron spectroscopy (XPS), or electron spectroscopy for chemical analysis (ESCA), is a material characterisation method that provides elemental and chemical information for solid sample with the analysing depth in few atomic layers.
