Modification of a Shockley-Type Surface State on Pt(111) upon Deposition of Gold Thin Layers
(MDPI, 2018-12-17)
We present a first-principles fully-relativistic study of surface and interface states in the n one monolayer (ML) Au/Pt(111) heterostructures. The modification of an unoccupied s - p -type surface state existing on a ...
Formation of Surface and Quantum-Well States in Ultra Thin Pt Films on the Au(111) Surface
(MDPI, 2017-12-09)
The electronic structure of the Pt/Au(111) heterostructures with a number of Pt monolayers n ranging from one to three is studied in the density-functional-theory framework. The calculations demonstrate that the deposition ...
Evidence for a Spin Acoustic Surface Plasmon from Inelastic Atom Scattering
(Nature, 2021-01-15)
Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can ...
