The influence of anions on the structure of underpotentially deposited Cu on Au(111): A LEED, RHEED and AES study
TL;DR: In this article, the underpotential deposition of Cu onto Au(111) in different electrolytes has been investigated by LEED, RHEED and AES, and ordered layers of (√3 × √3) R30° and (2.2 × 2.2) type were found for Cu at medium coverages in sulfate and perchlorate solutions, respectively.
Journal ArticleDOI
Oxygen-induced restructuring of Ag(111)

TL;DR: In this paper, the incorporation of oxygen atoms in subsurface sites causes a slight expansion of the topmost layer by about 3% which accounts for the formation of the observed moire pattern.
Journal ArticleDOI
A LEED and RHEED Investigation of Cu on Au(111) in the Underpotential Region
TL;DR: In this paper, the structure of Cu adsorbates, deposited electrochemically up to one monolayer onto Au(111) at underpotentials, has been investigated using LEED and RHEED after transfer of the gold electrode from the electrochemical cell into an UHV chamber.
Journal ArticleDOI
Deposition of monolayer and bulk lead on Ag(111) studied in vacuum and in an electrochemical cell
TL;DR: In this paper, the early stages of Pb condensation on Ag(111) have been studied in ultrahigh vacuum and in an electrochemical cell, and a particular case of Stranski-Krastanov type is found for the subsequent growth.
Journal ArticleDOI
On the stability of reconstructed gold surfaces in an electrochemical cell
TL;DR: In this article, a combined electrochemical and LEED, RHEED and AES study was conducted to reconstruct the Au(100), (111), and (110) surfaces in aqueous electrolytes under certain potential conditions.
