It is shown that niobium atoms are ordered to form a two-dimensional superstructure with equidistant spacing between the chains of niobium atoms. Chemical shifts of Nb3d- and O1s-levels demonstrate that the oxide layer corresponds to niobium monoxide NbO and the most part of oxygen in chemisorbed state is localized on the surface. A model of quasi-ordered structure of NbO on the Nb(110) surface is proposed Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Shalaeva, E. V.; Kuznetsov, M. V.
