(a) spectra for and thick silicate layers on the substrate after nitridation at calibrated with respect to Au reference sample. Inset: corresponding VB edges. The estimated electron escape depth is less than . (b) spectrum at for the nitrided silicate. Inset: VB spectra.
VB spectra for (a) and (b) nitridation series. In each case the spectra obtained at photon energy of (full circles) and (open circles) are shown. The vertical lines indicate the VB onsets, the shadow panels the different regions of the VB. The widths for the as-deposited silicate and the at are also shown. The binding energy scale has been corrected to account for final state and band-bending effects.
VB onsets for as deposited silicate (full circles); nitrided silicate (open circles); and fully etched silicate (triangles) at . The binding energy scale is corrected as in Fig. 2. Inset: modification of the VB offset by the states.
Experimental valence-band offsets for the silicate before and after nitridation.
