Au(111) and Pt(111) surface phase behavior

Surface Science Letters, 1993
Abstract We describe our recent X-ray scattering studies of the structure and phases of the clean Au(111) and Pt(111) surfaces. Below 0.65 of their respective bulk melting temperatures, the Au(111) surface has a well-ordered chevron reconstruction and the Pt(111) surface is unreconstructed.

Ag UPD on Au(100) and Au(111)

Electrochimica Acta, 1998
The underpotential deposition (UPD) of Ag in the systems Au(hkl)/Ag + , ClO - 4 and Au(hkl)/ Ag + , SO 2- 4 with (hkl) = (100), (111) was studied by in situ STM and different electrochemical techniques including charge-coverage measurements with the twin-electrode thin-layer (TTL) technique.

On-Surface Azide–Alkyne Cycloaddition on Au(111)

ACS Nano, 2013
We present [3 + 2] cycloaddition reactions between azides and alkynes on a Au(111) surface at room temperature and under ultrahigh vacuum conditions. High-resolution scanning tunneling microscopy images reveal that these on-surface cycloadditions occur highly regioselectively to form the corresponding 1,4-triazoles.

Adsorption and desorption of thermally generated hydrogen atoms on Au(111) and Ag/Au(111)

Surface Science, 2015
Abstract To explore the possibility of employing thermally generated H atoms to determine the chemical composition of a metallic surface, we investigated the adsorption and desorption of H atoms generated with a thermal cracker on surfaces Au(111) and Ag/Au(111).

Sulfur electroadsorption on Au(111)

Electrochimica Acta, 2004
Abstract In this paper, we have reviewed our results about S adsorption on Au(1 1 1) surfaces derived from electrochemical, in situ scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and surface X-ray diffraction (SXD) measurements.

Anodic oxidation of Au(111)

Canadian Journal of Chemistry, 1997
The initial stages of the anodic oxidation of Au(111) were investigated by means of cyclic voltammetry as well as in situ scanning tunneling microscopy (STM). The results suggest that the place exchange process, which initiates the oxide formation, starts at step edges.

EPITAXIAL GROWTH IN THE (111)Ag/Cu AND (111)Au/Cu SYSTEMS

Journal of Crystal Growth, 1975
Abstract The initial stages of epitaxial growth in the (111)Ag/Cu and (111)Au/Cu systems were investigated using UHV-RHEED and TEM on the same specimens. Flat, monocrystalline (111)Cu substrates, 1100 A thick, were formed in situ in the RHEED system on (111)NaCl/mica bilayers. The latter consisted of air-cleaved mica on which 150 A of NaCl was vacuum-

The resonance image states at Cu(111), Au(111), and Al(111) surfaces

Surface Science, 1991
Abstract Using the Green function approach the resonance image states at Cu(111), Au(111), and Al(111) surfaces were studied and the distributions of the density of states were calculated in the crystal surface region. It is shown that the crystal lattice potential influences the resonance image states and is responsible for the difference in their ...
