Research Abstract

Composition and chemical structures of high quality Si-SiO_2 systems formed using oxygen radicals and those of high quality Si-Si_3N_4 systems formed using nitrogen-hydrogen radicals were studied by measuring angle-resolved photoelectron spectra arising from Si 2p and O 1s core levels and valence band with the same probing depth.
