抄録(英) | The valence band structure of the ultra-thin SiO_2/Si(111) interface has been studied by high resolution x-ray photoelectron spectroscopy. The absence of Si^<2+> derived from the deconvolution of the Si 2p core-level peak implies an atomically flat interface mainly formed by Si^<1+>. The energy shifts found in the Si 2p and O 1s core-level peaks are induced by charging effects and have been corrected. The valence bands for the ultra-thin (1.8-3.7nm thick) SiO_2 are obtained after subtracting the substrate Si contribution from the measured spectrum and by taking into account charging effects. The valence band alignment of the ultra-thin SiO_2/Si(111) interfaces is found to be 4.36±0.10eV regardless of oxide tickness. |
