摘要X-ray-absorption near-edge structure (XANES) spectra of thin-film CoSi2 were measured at the Si K edge and Co L3 edge using the total electron yield mode. The Si K-edge results for CoSi2 showed a dramatic reduction of intensity in the first broad feature accompanied by a rise in a relatively strong and sharp feature at higher binding energies when compared to XANES spectra for crystalline Si. We attribute these two features to the Si 1s photoelectron excitations to a broad Si 3p nonbonding band and a relatively narrow band of hybridized Si p–Co 3d antibonding states, respectively. Analysis of the Co L3-edge white line spectra for CoSi2 reveals the appearance of a triple structure, which can be attributed to excitations to the unoccupied Co 3d nonbonding states and hybridized antibonding Co (3d,4s)–Si p states.
