Valence band states of H:GaAs(110)

Surface Science, 1994
The two-dimensional surface electronic band structure of H:GaAs(110) is studied by angular resolved ultraviolet photoemission spectroscopy along the XBAR'-MBAR and XBAR-MBAR symmetry lines and in the high symmetry points of the surface Brillouin zone. Three surface state bands are resolved in the first 5 eV below the upper valence band edge.

Electron valence band of zirconium tetrafluoride

Physical Review B, 1996
The partial p- and d-electron densities of states (DOS's) in the valence band of \ensuremath{\beta}-${\mathrm{ZrF}}_{4}$ were experimentally profiled through recording its Zr ${\mathit{M}}_{\mathrm{I}\mathrm{V},\mathrm{V}}$ and Zr ${\mathit{L}}_{\mathrm{II}}$ emission bands (spectra) by the x-ray spectrometer of an electron probe apparatus.

Magnetic band structure in the valence band of CdSb

Journal of Physics and Chemistry of Solids, 1984
Abstract Starting from the band structure calculations of Yamada, we have undertaken to calculate in analytic form the Landau levels, de Haas-Shubnikov oscillation periods and effective masses in the valence band of CdSb. Because of the anomalous character of the E — k relation in the x -direction, it is necessaryto use different approximation ...

Valence Band Structure of CdTe

physica status solidi (b), 1973
AbstractThe valence band structure near the I‐point in CdTe has been investigated. Experimentally, the absorption curves obtained for p‐type CdTe doped with Te, P, As are presented, discussed, and compared with theory [18]. This comparison yields the ratios of the hole effective masses m/m; = 7.5 and m/m = 5. The theoretical valence band structure near

The valence band of lithium fluoride

Journal of Physics C: Solid State Physics, 1973
The structure of the 2p F- valence band in LiF, as determined by high-resolution X-ray-induced photoelectron spectroscopy, is shown to be in good agreement with, though rather broader than, that calculated on the basis of the Hartree-Fock equation.

Features of valence band structure of

Journal of Physics: Condensed Matter, 1996
Modulation of the upper edge of valence band of ionic solids by occupied states of is a primary origin of the changes in optical and electrical properties of host materials containing . Semiquantitative estimation of mixing of states on ions with on ions in the crystal was carried out by photoemission, optical absorption, photoluminescence and ...

Valence band of graphite oxide

EPL (Europhysics Letters), 2010
We investigated the valence band structure of graphite oxide by photoelectron spectroscopy at the Pohang Accelerator Laboratory, Korea. The typical sp2 hybridization states found in graphite were also seen in graphite oxide. However, the π state disappeared near the Fermi level because of bonding between the π and oxygen-related states originating from

Extremely Shallow Valence Band in Lanthanum Trihydride

Journal of the American Chemical Society, 2022
Hydride ions (H-) in solvents are chemically active anions with strong electron-donating ability and are used as reducing agents in organic chemistry. Here, we evaluate the energy level of 1s-electrons in H- accommodated in solid lanthanum hydrides, LaHx (2 ≤ x ≤ 3), by photoemission (ultraviolet photoelectron and photoelectron yield spectroscopies ...

The XPS valence band of chromium

Philosophical Magazine B, 1984
Abstract The X-ray photoemission (XPS) spectra of the valence band and 2p core lines of metallic chromium are presented. A considerable deviation is observed in the shape of the valence band between the experimental spectrum and the theoretical one-electron spectrum.

Resonant valence-band satellite in NiGa

Physical Review B, 1995
Valence-band photoemission spectra of NiGa were measured with synchrotoron radiation at photon energies around the Ni 3p core excitation threshold. The valence-band satellite in NiGa is resonantly enhanced, and it has about the same Fano parameter and effective Coulomb interaction as those for elemental Ni. These observations suggest that the Ni d band
