On the electrochemical adsorption of KBr on gold (100); a LEED-Auger study

To determine the relationship between the electrochemical nature of the solid-liquid interface and its surface structure and composition, a transfer system coupling an electrochemical cell with a UHV analysis chamber was constructed. In this study we report the results of complimentary electrochemical and AES/LEED measurements of bromide ions adsorbed on an Au(100) electrode at various potentials, Our findings highlight the relationship between changes in surface composition and specific features observed in cyclic voltammetry (CV). In addition, the ability of electrochemistry to prepare unique surface structures that are inaccessible to conventional UHV deposition techniques is discussed.
