Abstract

A study of the effect of different heat treatments on the spreading of the MoO3 crystallites is presented by systematically varying the temperature, the total pressure, and the humidity of the oxygen atmosphere. The study concluded that a gas-phase transport mechanism is active for the spreading of MoO3 on a flat Al2O3 support under the chosen conditions.

43. A low-energy ion scattering study of Al(1 1 0) surface melting

Author

Pedemonte L., Bracco G., Beikler R., Taglauer E., Robin A., and Heiland W.

Abstract

The thermal behaviour of the (1 1 0) surface of aluminum is investigated by low-energy ion scattering along the and azimuthal directions in the temperature range between 300 and 910 K. Surface channeling mode and neutral impact collision ion scattering spectroscopy are used. Surface melting is observed and information on the evolution of the surface structure is gained with the help of simulations performed with the MARLOWE code. Experimental evidence for residual short range order is obtained along both azimuths within the quasi-liquid layer which probably consists of groups of surface atoms in correlated motion.

47. Crystal effects in the Neutralization of He+ ions in the low energy ion scattering regime

Author

Primetzhofer, Daniel, Markin, S. N., Juaristi Oliden, Joseba Iñaki, Taglauer, E., Bauer, P., Primetzhofer, Daniel, Markin, S. N., Juaristi Oliden, Joseba Iñaki, Taglauer, E., and Bauer, P.

Abstract

Investigating possible crystal effects in ion scattering from elemental surfaces, measurements of the positive ion fraction P+ are reported for He+ ions scattered from single and polycrystalline Cu surfaces. In the Auger neutralization regime, the ion yield is determined by scattering from the outermost atomic layer. For Cu(110) P+ exceeds that for polycrystalline Cu by up to a factor of 2.5, thus exhibiting a strong crystal effect. It is much less pronounced at higher energies, i.e., in the reionization regime. However, there a completely different angular dependence of the ion yield is observed for poly- and single crystals, due to massive subsurface contributions in nonchanneling directions.
