The Si L2,3 SXF spectrum obtained from a sample annealed at 750°C indicates an interface electronic structure composed with the compound of Cr3Si silicide and other materials, e.g., a ternary compound.
Among transition metals materials of chromium (Cr) and iron (Fe) are interesting for the electrodes such as a Schottky contact because of high electric contact resistance [1-3] compared with other transition metals.
For the sake of discussion, we have shown electron excited SXF spectra obtained from reference materials in Fig. 4: (a) FeSi, (b) β-FeSi2, (c) α-FeSi2 and (d) bulk SiC, where incident electron energy (Ep) is 4keV [5].
Electron excited Si L2,3 fluorescence spectra obtained from reference materials: (a) FeSi, (b) β-FeSi2, (c) α-FeSi2 and (d) bulk SiC.
