The atomic structure of alloy surfaces and surface alloys
TLDR
In this paper, the available data about the structure of bimetallic surfaces where the constituent elements are intermixed at atomic level is reviewed, including the surface of bulk alloys and systems resulting from diffusion at metal-metal interfaces.Abstract:
This paper reviews the available data about the structure of bimetallic surfaces where the constituent elements are intermixed at atomic level. These systems include the surface of bulk alloys ('alloy surfaces') and systems resulting from diffusion at metal-metal interfaces ('surface alloys'). All cases where a complete surface crystallographic determination exists are listed and discussed, as well as selected cases where the structural data are not complete but can lead to a model of the atomic structure.read more

Surface science studies of model fuel cell electrocatalysts
Nenad M. Markovic,Philip N. Ross +1 more
TL;DR: In this paper, the authors discuss progress in the understanding of electrocatalytic reactions through the study of model systems with surface spectroscopies and discuss the limitations of using pure metal single crystals and well-characterized bulk alloys as models for real catalysts.

A review on silicene - New candidate for electronics
Abdelkader Kara,Abdelkader Kara,Hanna Enriquez,Ari P. Seitsonen,L. C. Lew Yan Voon,Sébastien Vizzini,Bernard Aufray,Hamid Oughaddou,Hamid Oughaddou +8 more
TL;DR: In this paper, the existence of silicene has been achieved recently owing to experiments involving epitaxial growth of silicon as stripes on Ag (001), ribbons on Ag(110), and sheets on Ag((111) ).

Platinum Monolayer on Nonnoble Metal−Noble Metal Core−Shell Nanoparticle Electrocatalysts for O2 Reduction
Junliang Zhang,Fabio Henrique Barros de Lima,Minhua Shao,Kotaro Sasaki,Jia X. Wang,Jonathan C. Hanson,Radoslav R. Adzic +6 more
TL;DR: The results demonstrated that high-activity electrocatalysts can be devised that contain only a fractional amount of Pt and a very small amount of another noble metal.

Phase diagrams for surface alloys
Asbjørn Christensen,Andrei V. Ruban,Per Stoltze,Karsten Wedel Jacobsen,Hans Lomholt Skriver,Jens K. Nørskov,Flemming Besenbacher +6 more
TL;DR: In this paper, the authors discuss surface alloy phases and their stability based on surface phase diagrams constructed from the surface energy as a function of the surface composition and give self-consistent density-functional results for the segregation energy and surface mixing energy for all combinations of the transition and noble metals.

Embedded-atom method: Derivation and application to impurities, surfaces, and other defects in metals
Murray S. Daw,Michael I. Baskes +1 more
TL;DR: In this paper, the authors derived an expression for the total energy of a metal using the embedding energy from which they obtained several ground-state properties, such as the lattice constant, elastic constants, sublimation energy, and vacancy-formation energy.

Embedded-atom-method functions for the fcc metals Cu, Ag, Au, Ni, Pd, Pt, and their alloys.
TL;DR: A consistent set of embedding functions and pair interactions for use with the embedded-atom method was determined empirically by fitting to the sublimation energy, equilibrium lattice constant, elastic constants, and vacancy-formation energies of the pure metals and the heats of solution of the binary alloys as discussed by the authors.
