High resolution core level and valence band (VB) X-ray photoelectron spectra (XPS) of the non-conductor pyroxene minerals, bronzite ((Mg 0.8,Fe 0.2) 2Si 2O 6) and diopside (Ca(Mg 0.8Fe 0.2)Si 2O 6) have been obtained with the Kratos magnetic confinement charge compensation which ...
x-ray photoelectron spectraA X-ray photoelectron spectroscopy (XPS) of valence band (VB) and core levels are performed for a SiO2/p-Si heterostructure containing a thin oxide layer of d=20nm thickness and implanted by Si+ ions. With an implantation energy of 12keV the maximum density of ...
42the DOS shows the valence and conduction bands for NaNbO3is comprised of the O 2porbitals and Nb 4dorbitals respectively, resulting in a band gap of ∼3.4eV. The conduction band of AgNbO3is similarly formed by the empty 4dorbitals of Nb, but the valence band edge is here comprised ...

The x-ray photoemission valence band spectra of NbC have been measured and are compared with the x-ray emission spectra and with the results from band structure calculations. This comparison leads to a large enhancement of the C 2 p photoabsorption cross section (at 蠅 =1,487 eV) compared ...
Core and valence band spectra were obtained from a commercial PbO. The XPS data were collected with a VSW HA150 spectrometer equipped with a monochromatic ... Rondon,Sonia - 《Surface Science Spectra》 被引量: 22发表: 1998年 Chemical effect on the XPS spectra of the valence band and on O...
46, 645 (1992)] showed that XPS valence band spectra were more sensitive to chemical environment on the carbon fiber surface than core level spectra and could be well interpreted by X–α calculations with model compounds. In this work, the val... 展开 ...
