d—s, p Resonance and Electronic Structure of Compounds, Alloys, and Solid Solutions

Abstract

On the basis of the valence band structure regularities, obtained from combined X-ray spectral and X-ray photoelectron studies of electron energy spectra, a model is suggested for the interaction between valence electrons of s,

XPS and theoretical studies of the electronic structure of FeX and NiX (X = Al, Si, P)

“…The maximum of d(Ni) states becomes a minimum of p(Si) states, which is typical for d-p resonance. 6 The states of the second region (at 2.5-5 eV) take part in d(Ni)-p(Si) hybridization. Unlike FeSi near E f , p(Si) states make a greater contribution.…”

Numerical simulation of a UV He—Ar—N2gas-discharge laser

“…Nevertheless, a first attempt to understand the energy band structure was based on pseudopotential calculations, whereas the structure of Cd 3 As 2 was approximated with that of the fluorite [2]. While the results were generally in accord with the experimental findings, the shape of the valence bands showed some deviation from what has been suggested by experiments [5,6]. Later on, the band structure of different II-V semiconductors including Cd 3 P 2 , Zn 3 P 2 , Cd 3 As 2 and Zn 3 As 2 was revisited by Sieranski et al [7], who performed semi-empirical tight-binding calculations, in which the crystal structure was approximated with a zincblende one, instead.…”

Valence-Band Structure Features of Nickel Disilicide Films

“…Therefore, the Si-L 1 spectrum is slightly narrower than the K b spectrum, with more distinctly expressed features. The characteristic two-peak structure of these spectra is explained by the effect of d±s, p-resonance [30]. According to our calculation Ni dstates, interacting with s-and pstates of Si, split them into two components with a minimum in the area of localization of the nickel d-states, as it is shown in Figs.…”
