On the adsorption of oxygen on the Mo{110} surface and its vicinals

The adsorption of oxygen on a Mo{110} surface and four vicinal planes with steps parallel to 〈100〉, 〈110〉 and 〈111〉 directions, is studied by Auger electron spectroscopy (AES) and low energy electron diffraction (LEED). The work has the goal to elucidate whether O adsorption on Mo{110} is really as different from O adsorption on W{110} as reported, and what is the cause of the apparent discrepancies between the various reported sticking coefficients on stepped surfaces.
