Abstract
The influence of hydrogen on the growth of Y on Ni(001) and Ni(110) at room temperature is studied by full-hemispherical X-ray photoelectron diffraction and X-ray photoelectron spectroscopy. We find that Y star ts to form a hydride at a thickness of about 25 Angstrom when evaporat ing Y under a 10(-6) mbar hydrogen partial pressure. At the same time a weak ordering of the hydride on Ni is observed in the form of a pref erential orientation. No ordering occurs for evaporation without hydro gen in ultra-high vacuum.
