TL;DR: In this paper, a phenomenological theory of non local electrodynamics of metal/film systems is given in terms of a specularity parameter p for arbitrary 0 ~ p ~ 1 and applied to study the differential reflectivity of Ag films on an Al substrate.

TL;DR: In this paper, it was pointed out that the theorem of factorization of the surface Green function, previously proved for the eigenvalue problem of the Hamiltonian, applies generally for a surface which separates two media.

TL;DR: In this paper, a new reconstruction of Sn on silicon and observe a reversible transition where the surface unit cell divides its area by a factor of 4 at 250 degrees C. This phase transition is explained by the 24-fold degeneracy of the ground state and a novel diffusive mechanism, where four Sn atoms arranged in a snakelike cluster wiggle at the surface exploring collectively the different quantum mechanical ground states.

TL;DR: In this article, a unified simple model for clean, etched and reactive metal-semiconductor junctions is proposed, where the selfconsistent redistribution of charge at the junction and its density of states are analyzed as a function of the interface conditions.

TL;DR: In this article, the correlation effects associated with the dangling bond surface states of Si(111)-5×5, Si( 111)-7×7 and Sn Ge (111) -3×3 are analyzed.
