Abstract:Ionization and Auger spectroscopy show that a submonolayer coating of bismuth on Si(001) reduces the initial attachment coefficient for molecular oxygen by comparison with a clean Si(001) surface by two orders of magnitude, while exposure to >105 Langmuir of O2 causes bismuth to stimulate the formation of surface silicon oxide having stoichiometry close to SiO2.
