J. Matthias Kahk, Georg S. Michelitsch, Reinhard J. Maurer, Karsten Reuter, Johannes Lischner, J. Phys. Chem. Lett. 12, 9353-9359 (2021)

"We present an approach to calculate accurate core electron binding energies of a variety of materials based on Delta-self-consistent-field calculations that are referenced to the valence band maximum. We further show that the resulting simulations provide excellent agreement with experimental X-ray photoemission spectroscopy data."

The Nuts and Bolts of Ab-Initio Core-Hole Simulations for K-shell X-Ray Photoemission and Absorption Spectra

B. Klein, S. J. Hall, R. J. Maurer, J. Phys. Condens. Matter 33, 154005 (2020)

"We present the numerical and technical details of our variants of the DeltaSCF and transition potential method (coined DeltaIP-TP) to simulate XPS and NEXAFS transitions. Using exemplary molecules in gas-phase, in bulk crystals, and at metal-organic interfaces, we systematically assess how practical simulation choices affect the stability and accuracy of simulations. We particularly focus on the choice of aperiodic or periodic description of systems and how spurious charge effects in periodic calculations affect the simulation outcomes. For the benefit of practitioners in the field, we discuss sensible default choices, limitations of the methods, and future prospects."
