Abstract

The formation of Co atomic chains on a Cu(775) surface is investigated by the kinetic Monte Carlo method. It is found that the length of Co atomic chains formed as a result of self-organization during epitaxial growth is a random quantity and its mean value depends on the parameters of the experiment. The existence of two structural phases in atomic chains is detected using the density functional theory. In the first phase, the separations between an atom and its two nearest neighbors in a chain are 0.230 and 0.280 nm. In the second phase, an atomic chain has identical atomic spacings of 0.255 nm. It is shown that the temperature of the structural phase transition depends on the length of the atomic chain.

Smeared spin-flop transition in random antiferromagnetic Ising chain

Journal Article

At T = 0 and in a sufficiently large field, the nearest-neighbor antiferromagnetic Ising chain undergoes a first-order spin-flop transition into the ferromagnetic phase. We consider its smearing under the random-bond disorder such that all independent random bonds are antiferromagnetic (AF). It is shown that the ground-state thermodynamics of this random AF chain can be described exactly for an arbitrary distribution P(J) of AF bonds. Moreover, the site magnetizations of finite chains can be found analytically in this model. We consider a continuous P(J) that is zero above some -J{sub 1} and behaves near it as (-J{sub 1}-J){sup {lambda}}, {lambda}more »« less

Scanning tunneling microscopy study of formate species synthesized from CO{sub 2} hydrogenation and prepared by adsorption of formic acid over Cu(111)

Journal Article Fujitani, T; Choi, Y; Sano, M; ... - Journal of Physical Chemistry B: Materials, Surfaces, Interfaces, amp Biophysical

The adsorption structure of formate species on Cu(111), prepared by two different methods, was studied using ultrahigh vacuum scanning tunneling microscopy (UHV-STM), that is, the synthesis by the hydrogenation of CO{sub 2} at atmospheric pressure and the adsorption of formic acid on an oxygen-precovered Cu(111). Linear chains of formate molecules were imaged by the hydrogenation of CO{sub 2} by STM at low formate coverage with the distance to the nearest neighbor of the formate species estimated to be 5.0 {+-} 0.2{angstrom}, twice that of the nearest Cu--Cu neighbor. The adsorption phase of formate thus grows linearly at the initial stagemore »« less

Atom-wide Co Wires on Cu(775) at Room Temperature

Journal Article Johnson, P; Zaki, N; Potapenko, D; ... - Physical Review. B, Condensed Matter and Materials Physics

We report on a surface phase of the Co-vicinal-Cu(111) system which exhibits self-assembled uniform Co quantum wires that are stable at 300 K. Scanning tunneling microscopy (STM)-imaging measurements show that wires will self-assemble within a narrow range of Co coverage and, within this range, the wires increase in length as coverage is increased. The STM images show that the wires form along the leading edge of the step rise, differentiating it from previously theoretically predicted atomic-wire phases. The formation of relatively long laterally unencapsulated one- and two-atom wires also differentiates it from past experimentally observed step-island formation. Furthermore, our experimentsmore »« less
The characterization of organic monolayers at gold surfaces using scanning tunneling microscopy and atomic force microscopy correlation with macrostructural properties

Technical Report Alves, C

Monolayer films formed by self-assembly of organothiols at epitaxially grown Au(111) films at mica were examined in air using scanning tunneling (STM) and atomic force microscopies (AFM). n-Alkanethiolate monolayers exhibit a hexagonal packing arrangement with nearest-neighbor and next-nearest-neighbor spacings of 0.50 and 0.87 nm. This arrangement is consistent with the ([radical]3 [times] [radical]3)R30[degrees] adlayer structure at Au(111). STM reveals the structure of the Au-bound sulfur, while AFM details the structure at the monolayer/air interface, revealing that the order at the Au-S interface is retained up to the monolayer/air interface. The investigation of the self-assembled CF[sub 3](CF[sub 2])7(CH[sub 2])[sub 2]SH monolayermore »« less
