Iron oxide thin films prepared by ion beam induced chemical vapor deposition: Structural characterization by infrared spectroscopy
(AVS Science and Technology Society, 2000)
Iron oxide thin films as hematite (α-Fe2O3) have been prepared by ion beam induced chemical vapor deposition. Very compact and dense films are obtained by this procedure. The thin films have been grown by ombardment of the ...

Ab initio x-ray absorption study of copper K -edge XANES spectra in Cu(II) compounds
(American Physical Society, 2005)
This work reports a theoretical study of the x-ray absorption near-edge structure spectra at the Cu K edge in several Cu(II) complexes with N -coordinating ligands showing a square-planar arrangement around metal cation. ...

Electronic structure of stoichiometric and Ar+-bombarded ZrO2 determined by resonant photoemission
(American Institute of Physics Publising LLC, 1995)
The electronic properties of thermally grown ZrO2 thin films before and after Ar+ bombardment have been studied with resonant photoemission spectroscopy using synchrotron radiation. For stoichiometric ZrO2 thin films the ...

Effects of nonstoichiometry in the melting process of Y2O3 from molecular dynamics simulations
(American Physical Society, 1999)
Molecular dynamics simulations in the microcanonical ensemble of liquid yttrium oxide were performed at a temperature of 3100 K. Three different Y/O ratios were used in order to find out what the role of nonstoichiometry ...

Near edge x-ray absorption fine structure spectroscopy study of atomic nitrogen implanted in Al2O3 by low energy N2+ bombardment
(AVS Science and Technology Society, 2001-05)
N2+ bombardment of Al2O3 has been investigated by near edge x-ray absorption fine structure spectroscopy. Two kinds of species were detected and were attributed to implanted nitrogen atoms and nitride species. These results ...

Operando XAS and Raman study on the structure of a supported vanadium oxide catalyst during the oxidation of H2S to sulphur
(Elsevier, 2010)
The modification of crystalline phases of a vanadium oxide supported on mesoporous zirconium phosphate during the partial oxidation of H2S to sulphur has been studied by using an operando Raman-GC approach and XAS in ...
