CARBON, NITROGEN, AND SULFUR ON NI(111) - FORMATION OF COMPLEX STRUCTURES AND CONSEQUENCES FOR MOLECULAR DECOMPOSITION Academic Article uri icon

abstract

  • The decomposition of simple amines on Ni(111) produces a c(53 9)rect LEED pattern similar to the one reported earlier after reaction of H2S, C2H4, CO, NO and CH3CN on a Ni(111) surface. We have measured LEED IV curves of the structure obtained after deposition of carbon and nitrogen on a Ni(111) surface. The similarity between these IV curves shows that carbon and nitrogen have similar local geometries. The most intense spots of the c(53 9)rect LEED pattern are explained by the formation of a (100) orientation nickel monolayer, with the carbon or nitrogen atoms in the 4-fold hollow sites. This is supported by the qualitative similarity of the IV curves with those of the Ni(100)-(2 2)-2C structure. We have also produced a (2 6) nitrogen induced structure on Ni(111) and compared it to the very similar (53 2)rect structure obtained by adsorption of sulfur on Ni(111) that has also been interpreted as due to a (100) reconstruction of the Ni(111) crystal surface. 1993.
