“…Plasmon loss can be described as the loss of kinetic energy of the photoelectron (increase in BE) arising from an oscillation of bound valence electrons [49]. This assignment has been corroborated by identifying the occurrence of the same phenomenon in most of the firstrow transition metals (Sc-Ni) [50][51][52][53][54]. Note that no such plasmon loss peak is observed in the Mn or V 2p 3/2 spectra, likely because it is overlapped by the significantly more intense core-line.…”

“…The amplitude of the plasmon loss peak observed in the Co 2p 3/2 spectra has been shown to vary greatly with only a slight change in the occupancy of the Co valence states [21,55]. Analysis of the 1s XPS peak of the series Sc-Co using a Cu Ka X-ray source also revealed that the plasmon loss peak intensifies with greater number of spin-unpaired electrons, and that the energy separation between the plasmon loss peak and the core-line increases with greater concentration of 3d valence electrons [54]. The intensity of the plasmon loss peak is more sensitive than the energy of the plasmon loss peak or the 2p 3/2 core-line BE to changes in the occupancy of the valence states.…”

“…41 To better account for unquantized ͑extrinsic͒ plasmon energy losses, we leave the inelastic-scattering B coefficient as a fitting parameter. 42 We simulated the spectral line shapes with the aid of the CASAXPS software package. Figure 3͑b͒ shows the analysis of the Mn 2p photoemission line shape for the MnAs nanoclusters, based on the CI cluster model.…”

Enhanced electron correlations, local moments, and Curie temperature in strained MnAs nanocrystals embedded in GaAs

We have studied the electronic structure of hexagonal MnAs, as epitaxial continuous film on GaAs͑001͒ and as nanocrystals embedded in GaAs, by Mn 2p core-level photoemission spectroscopy. Configurationinteraction analyses based on a cluster model show that the ground state of the embedded MnAs nanocrystals is dominated by a d 5 configuration that maximizes the local Mn moment. Nanoscaling and strain significantly alter the properties of MnAs. Internal strain in the nanocrystals results in reduced p-d hybridization and enhanced ionic character of the Mn-As bonding interactions. The spatial confinement and reduced p-d hybridization in the nanocrystals lead to enhanced d-electron localization, triggering d-d electron correlations, and enhancing local Mn moments. These changes in the electronic structure of MnAs have an advantageous effect on the Curie temperature of the nanocrystals, which is measured to be remarkably higher than that of bulk MnAs.

Hard X-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential technique for the characterisation of materials. The number of specialised photoelectron spectroscopy techniques making use of hard X-rays is steadily increasing and ever more complex experimental designs enable truly transformative insights into the chemical, electronic, magnetic, and structural nature of materials. This paper begins with a short historic perspective of HAXPES and spans from developments in the early days of photoelectron spectroscopy to provide an understanding of the origin and initial development of the technique to state-of-the-art instrumentation and experimental capabilities. The main motivation for and focus of this paper is to provide a picture of the technique in 2020, including a detailed overview of available experimental systems worldwide and insights into a range of specific measurement modi and approaches. We also aim to provide a glimpse into the future of the technique including possible developments and opportunities.
