Adsorption of oxygen on the {111}, {100} and {110} surfaces of clean nickel

Growth and characterization of nickel oxide ultra-thin films

“…1c). This LEED pattern is quite similar to that observed by Munoz-Marquez et al [21] when a clean Ni(111) surface, heated in the range of 550-600 K, receives much higher exposure rates (several cycles of 1200 L).…”

“…Let us recall that the entire process was performed under ultrahigh vacuum conditions, and the oxidation process was performed by RT exposure to pure molecular oxygen followed by post-annealing. It is generally agreed [18,21] that the initial ordered phases form by the dissociative chemisorption of the oxygen molecules. Nickel is commonly used as a catalyst to dissociate water, forming OH and H on the surface [35].…”

Reconstruction of Clean and Adsorbate-Covered Metal Surfaces

“…It is important to note that the adsorbate-induced missing row reconstruction is not a universally observed phenomenon on fcc {110} surfaces. Adsorption of atomic oxygen onto Ni and Cu {110} surfaces gives rise to a (2 ×1) added row reconstruction. − The removal of alternate Cu atoms along [11̄0] produces missing rows running in the [001] direction, i.e. perpendicular to the close-packed rows and to the missing rows discussed previously, and the adsorption of oxygen atoms in long bridge sites leads to a structure made up of added Cu−O chains along [001]. − A quantitative LEED study on the O−Cu system shows that multilayer relaxations are again important 92 (Figure ).…”

Study of O/Ni(100) with LEED and AES: from chemisorption to oxidation

“…Some poisoning [2] or promoting [1] The first of 0/Ni(100) was done by MacRae [8], who studied all three lowindex faces -(100), (111) and (110) [19]. The formation of p(2x2) structure is accompanied by a +2% expansion between the top two Ni layers, and the c(2x2) is accompanied by a larger relaxation of +5% [10,11], which has been increased to +5.7% by the most recent study [19].…”
