The azimuthal dependent oxidation process on Cu(110) by energetic oxygen molecules

We report a study on the oxidation process induced by a hyperthermal oxygen molecular beam (HOMB) on Cu(110) using X-ray photoemission spectroscopy in conjunction with a synchrotron radiation source. The oxidation process induced by energetic O-2 beams on Cu(110), depending on the azimuthal angle of incidence, suggests that the -Cu-O- added row structure has a role in inhibiting adsorption as a steric obstacle for incident O-2 molecules.
