摘要
High-resolution Si 2p core level photoemission spectra of the SiO2/Si(111) system show chemically shifted components derived from individual oxidation states, which exhibit strong intensity modulations as a function of photon energy due to final-state diffraction. Analysis of these photoemission intensity modulations gives bond-length information specific to the individual suboxide. The results indicate that the interface is atomically abrupt.
