Endohedrally Doped Cage Clusters
TL;DR: This comprehensive review presents results of many such developments in this fast-growing field including endohedrally doped Al, Ga, and In clusters, and performs ab initio calculations to present updated results of the most stable atomic structures and fundamental electronic properties of the endohedral doped cage clusters.

Surface segregation of Si on Fe single crystal surfaces and interaction with carbon
H. De Rugy,Helmut Viefhaus +1 more
TL;DR: In this article, the authors applied AES and LEED to the study of silicon surface segregation on Fe−3wt%Si single crystals between 400 and 900°C, and showed that the repelling of Si by C on the surface is mainly due to a site competition reaction, whereby the strong Si-C repulsive interaction plays a minor role.

Calculation of surface free energies and characteristics of surface segregation of solids
L.Z. Mezey,J. Giber +1 more
TL;DR: In this paper, the generalized surface free enthalpy is defined for any (equilibrium or nonequilibrium) segregation profile and its γ ∗ minimal value is connected with the segregation profile of the stable equilibrium state.

Neutral and negatively charged Al 12 X ( X=Si , Ge, Sn, Pb) clusters studied from first principles
Sheng Li,Sheng Li,Xiu-Fang Gong +2 more
TL;DR: In this paper, the ground states of neutral and anionic ionic clusters were analyzed and it was shown that both neutral and charged ionic cluster prefer icosahedral structure, in agreement with previous calculations.

Binary alloy surface compositions from bulk alloy thermodynamic data
Frank L. Williams,D. Nason +1 more
TL;DR: In this paper, the surface composition of binary alloys is determined by minimizing alloy surface free energy with respect to atom exchange between the surface and the bulk, using a pairwise bound model of the solid with a broken bond surface.

Surface energy and solute strain energy effects in surface segregation
Paul Wynblatt,R. Ku +1 more
TL;DR: In this paper, a unified formalism of surface segregation was proposed for grain boundary segregation based on the reduction in lattice strain energy which accompanies the transfer of misfitting solute atoms from the lattice to the boundary.
