Formation of a new type of chromium oxide by deposition of chromium onto water precovered Cu(111)

X-rays diffraction on a new chromium oxide single-crystal thin film prepared by molecular beam epitaxy

“…This oxide can only exist in monolayer and a-Cr 2 O 3 was formed while further growth of the layer. However, the lattice constant, 3.818 Å , deduced from CrO(1 1 1) formed on D 2 O precovered Cu(1 1 1) [4], was much smaller. The lattice constant of a hypothetical CrO, by comparing with NaCl-type oxides and nitrides of the neighbouring metals (V, Ti), was estimated to be 4.08 Å .…”

“…Maetaki et al [2,3] reported that they obtained one monolayer of CrO, (1 1 1) oriented on Cu(1 0 0) and Cu(1 1 1) substrates by deposition of chromium atoms and subsequent exposure to oxygen in vacuum. Pantfo¨rder et al [4] evaporated Cr atoms on D 2 O precovered Cu(1 1 1). They obtained 1-6 ML CrO, also (1 1 1) oriented, after the samples were annealed at 750 K. However, all the above-mentioned films can only exist in surface structures.…”

Self-organized chromium oxide monolayers on Fe(001)

“…43 Another example is given by Cr deposition onto a water precovered Cu(111) surface, a procedure that leads to the stabilization of a new type of chromium oxide with a square two-dimensional lattice. 44 In this paper we show how the Fe(001)-p( …”

Growth of stoichiometric subnanometer silica films

“…6 The use of different oxidants can further influence the stoichiometry and morphology of the oxide films. Metal deposition on water/ice layers can produce three-dimensional oxide particles 7 or films, 8 while deposition in oxygen generally leads to the formation of homogenous films. 1 The initial step in the oxidation of Si by water has been studied, 9 but further knowledge on the influence of water during the growth of oxide films is required.…”
