“…Band structure and charge density difference plots were practically identical to those of previous calculations [2][3][4][5][6][7] . For the energy-partitioning analysis the Ψ n were projected [23][24][25][26] onto a set of overlapping atom-localized non-orthogonal orbitals.…”

The contributions of the covalent bond energies of various atom pairs to the cohesive energy of MgB2 and AlB2 are analysed with a variant of our recently developed energy-partitioning scheme for the density-functional total energy. The covalent bond energies are strongest for the intralayer B-B pairs. In contrast to the general belief, there is also a considerable covalent bonding between the layers, mediated by the metal atom. The bond energies between the various atom pairs are analysed in terms of orbital-and energy-resolved contributions. 71.15.Nc,71.20.Gj,74.25.Jb,74.72.Yg

“…We performed a resonant inelastic X-ray scattering experiment by exciting the SXE close to the B 1s absorption threshold, and have observed low-energy electronic excitations. Our results are in broad agreement with contemporaneous synchrotron radiation-excited [25] and electron beam-excited SXE studies [26].…”

PACS. 74.25.Jb -Electronic structure. PACS. 78.70.Dm -X-ray absorption spectra. PACS. 78.70.En -X-ray emission spectra and fluorescence.Abstract. -The occupied and unoccupied valence band states of MgB2 have been studied using high-resolution soft X-ray emission and soft X-ray absorption spectroscopies. In particular, the B 2p partial density of states was measured near the Fermi level. The states at the Fermi edge are identified by comparison to calculation as being of B 2pxy origin. Resonant inelastic X-ray scattering indicates the existence of low-energy excitations at the B 1s-edge absorption threshold.

“…In particular, a large body of experimental data on the electronic structure of strongly correlated compounds of d and f metals [110][111][112][113][114][115][116][117][118][119], fullerenes [6,[120][121][122][123], molecular magnets [124][125][126][127], and new layered MgB 2 -type superconductors [31,[128][129][130][131][132] is left beyond the scope of this review, as is the influence of polarization effects on RIXS spectra [133−138]. The method in question is expected to progress along several lines.…”

This review focuses on the capabilities and potential of soft x-ray fluorescence spectroscopy for the study of the electronic structure and chemical bonding of novel materials. The basic principle of x-ray fluorescence measurements using synchrotron radiation and the corresponding instrumentation issues are outlined. Particular attention is given to x-ray spectroscopic studies of the electronic structure and characterization of nanostructures, thin films, interfaces, adsorbates, half-metallic ferromagnets, and impurities in alloys, superconductors, and semiconductors and the chemical bonding in biomaterials and liquids.
