C. Sanchez et Epm. Leiva, Cu underpotential deposition on Au(111) and Au(100). Can this be explainedin terms of the energetics of the Cu/Au system?, ELECTR ACT, 45(4-5), 1999, pp. 691-697
In this work we undertake a first principles study of the deposition of Cop
per on Au(111) and Au(100) surfaces from a density functional point of view
: The analysis of the different energetic contributions to the so-called un
derpotential shift indicates that the deposition of Cu on any of these surf
aces should occur at overpotentials. We conclude that some other factors mu
st be taken into account to explain the experimental results, such as anion
coadsorption. We also analyze the work function and the electronic density
in the system. (C) 1999 Elsevier Science Ltd. All rights reserved.
