    Exoelectron emission during oxidation of Cs films (1991)

    Notes: During oxidation of thin Cs films, a nonadiabatic surface reaction manifests itself in the emission of electrons. This effect was investigated in detail by combining measurements of the current and of energy distributions of these exoelectrons with studies on the electronic properties of the surface by means of ultraviolet photoelectron spectroscopy and metastable deexcitation spectroscopy. Exoelectron emission occurs via Auger deexcitation of the empty state derived from the O2 affinity level. This process is confined to the stage Cs2O2→CsO2 in which resonance ionization of the affinity level of the impinging O2 molecule upon crossing the Fermi level EF is efficiently suppressed due to the absence of metallic states near EF. A kinetic model based on the successive steps involved in the oxidation of Cs is developed which describes qualitatively well all the experimental findings.

    Characterization of oxygen phases created during oxidation of Ru(0001) (2000)

    Notes: Thermal desorption spectroscopy, ultraviolet photoelectron spectroscopy, low energy electron diffraction (LEED), and the reactive scattering of a CO molecular beam have been applied to determine the relationship between the formation of the subsurface oxygen phase and the growth of oxides during oxidation of Ru(0001). Emission of RuOx (x〈4) molecules observed in the thermal desorption spectra during the heating of the oxygen-rich sample has been used as a simple measure for the presence of bulk oxides. When performing the oxygen exposure at a temperature lower than the onset for oxygen desorption (Tp〈850 K) a mobile atomic oxygen species is predominantly formed in the subsurface region. The conversion of these subsurface oxygen atoms into a regular RuxOy phase takes place within the temperature region of 900–1150 K. The growth of oxide films becomes the dominating reaction channel when performing the oxidation at temperatures higher than the onset for oxygen desorption. The oxide formation is strongly reduced when conducting the oxidation at temperatures higher than 1250 K. In this case only a relatively low amount of oxygen atoms adsorbed on the bare Ru surface can be achieved, neither oxides nor subsurface oxygen have been found. The presence of a RuO2 coating layer manifests itself by LEED patterns characteristic for a particular RuO2 single crystal face as well as by additional features in the valence ultraviolet photoelectron spectra. The oxidation of CO molecules reactively scattered at these oxygen-rich surfaces proceeds as long as mobile oxygen atoms are present in the subsurface region. The reaction is entirely quenched when the subsurface oxygen is replaced by an uniform film of RuO2. © 2000 American Institute of Physics.

    Notes: Abstract LetAP Σ + (R n ) denote the Banach algebra of all continuous almost periodic functions onR n whose Bohr-Fourier spectrum is contained in an additive semi-group Σ⊂[0, ∞) n . We show that the maximal ideal space ofAP Σ + (R n ) may have a nonempty corona and we characterize all Σ for which the corona is empty. Analogous results are established for algebras of almost periodic functions with absolutely convergent Fourier series.

    The spectrum is discontinuous on the manifold of Toeplitz operators (2000)
    Springer

    Notes: Abstract. We answer in the negative a question by Farenick and Lee as to whether or not the spectrum is a continuous set-valued function on the linear space of Toeplitz operators. Thus, we show that if $\{a_n\}$ is any sequence of $L^\infty $ functions which converge uniformly to a function $a \in L^\infty $ , then the spectra of the Toeplitz operators T(a n ) need not converge to the spectrum of the Toeplitz operator T(a) in the Hausdorff metric. The counterexample is constructed with semi-almost periodic functions a n and a.
