摘要
The Si L-2,L-3-spectra of thin films of transition d-metal (TM) silicides (d-silicides) obtained by the ultrasoft X-ray emission spectroscopy (USXES) method have been analyzed on the basis of our d-s,p resonance model. Different stoichiometric composition silicides were obtained depending on the annealing conditions of heterostructures TM/Si mono TM/SiO2/Si mono. Compared with the spectra of the bulk samples, Si L-2,L-3-spectra of thin film silicides demonstrate an increased intensity in the high energy range near the Fermi level. The unique sharp intensive peak of the Si s-state at the Fermi level is a consequence of the distinction of d-s resonance in NiSi2. (C) 1998 Elsevier Science B.V. All rights reserved.
