Nearly-grazing-incidence-high-temperature sputtering of Ruthenium(0001) surface
2021, Applied Surface ScienceGas-solid catalytic reactions over ruthenium-based catalysts
2016, Cuihua Xuebao/Chinese Journal of CatalysisCitation Excerpt :H. Over et al. [18] demonstrated that the active part of this “O-rich” Ru phase is RuO2, which grows epitaxially with its (110) plane parallel to the Ru (0001) surface at high O2 partial pressure and elevated temperatures. When the Ru (0001) surface is exposed to molecular oxygen under UHV conditions, a (2×2)-O layer and a (2×1)-O overlayer are formed [19]. At much higher concentrations of oxygen, for example, more than 1 000 L at room temperature, the Ru (0001) surface stabilizes two additional phases of chemisorbed oxygen, namely, (2×2)-3O and (1×1)-O [20].
Lateral interactions and non-equilibrium in surface kinetics
2016, Surface ScienceCitation Excerpt :Evidence for fast and peaked products has been given very early [36], and additional information on this effect, mostly from molecular beam experiments, is plentiful [37]. Also, vibrationally and rotationally hot product molecules have been reported [38]. Our investigation was carried out within a program to check whether products of desorption and reaction contained equilibrated internal degrees of freedom.

2013, Surface ScienceCitation Excerpt :Hydrogen has been studied using a variety of experimental techniques, including low-energy electron diffraction (LEED) [31–33], scanning tunneling microscopy (STM) [34,35], high resolution electron energy loss spectroscopy (HREELS) [36–39], thermal desorption spectroscopy (TDS) [38], photoemission spectroscopy [40], and theoretical calculations [41–43]. Atomic oxygen has been studied with LEED [44], LEED-IV [45,46], surface X-ray diffraction (SXD) [47], HREELS [48–50], STM [51,52], TDS [53,54] and density functional theory (DFT) calculations [44,55]. Nitrogen has been studied with TDS [56,57], LEED [57,58], HREELS [56,57], STM [59,60], and DFT [42,61].
