We report on the various phases formed by sulfur adsorbed on Au(111), at less than 1 monolayer (ML) coverage, as monitored by low-energy electron diffraction (LEED). The phases transform from one to another via coexistence regions. The observation of

Substitutional adsorption geometry for Pb(111)–(√3×√3)R30°–K

Autor: Nicola Ferralis, Renee D. Diehl, M. Caragiu, F.M. Pan

Publikováno v: Surface Science. 600:537-541

Intermixed structures for alkalis (larger than Li) on close-packed substrates have previously been observed only on Al(1 1 1). This study shows that K forms an ordered intermixed structure on Pb(1 1 1). The structures of clean Pb(1 1 1) and Pb(1 1 1)

Alkali metal adsorption on graphite: a review

Autor: Sharon Finberg, M. Caragiu

Publikováno v: Journal of Physics: Condensed Matter. 17:R995-R1024

The adsorption of alkali metals on graphite has been the subject of various studies for the past two decades. Briefly, two main reasons can be offered to justify the persisting interest in these adsorption systems. First, experiments have pointed out

The adsorption sites of rare gases on metallic surfaces: a review

Publikováno v: Journal of Physics: Condensed Matter. 16:S2839-S2862

During the past six years, the adsorption geometries of several rare gases in structures having several different symmetries on a variety of substrates were determined using low-energy electron diffraction (LEED). In most of these studies, a preferen

An alternative method of using combined-space method: high index surfaces

Autor: Matti Lindroos, K. Pussi, M. Caragiu, Renee D. Diehl

Publikováno v: Surface Science. 544:35-44

This paper presents an alternative method for calculating I ( E )-spectra for a high index crystal surface using the SATLEED (symmetrized automated tensor-LEED) program. Two test structures, Cu{2 1 1} and Cu{2 1 1}-c(2 × 2)-Cs, have been analyzed. T

Adsorption geometry of Cu(110)-(12 × 2)-14Xe

Autor: Th. Seyller, M. Caragiu, Renee D. Diehl

Publikováno v: Surface Science. 539:165-170

Low-energy electron diffraction was used to study the adsorption geometry of Xe on Cu(1 1 0). At low temperatures, a higher-order commensurate (12 × 2) structure can be formed that consists of rows of Xe atoms aligned along the direction of the rows

LEED study of the potassium-induced reconstruction of Cu(110)

Autor: Katharina J. Franke, Renee D. Diehl, Nicola Ferralis, M. Caragiu

Publikováno v: Journal of Physics: Condensed Matter. 13:3961-3967

We have used low-energy electron diffraction (LEED) to determine the adsorption geometry of the ordered p(2×2) potassium overlayer on the (potassium-induced) (1×2) missing-row reconstruction of Cu(110) at 47 K. The K adsorption site in this ordered

The adsorption geometry of Ag(111)–(√7×√7)R19.1°-4Ar studied by LEED

Autor: M. Caragiu, G. S. Leatherman, Th. Seyller, Renee D. Diehl

Publikováno v: Surface Science. 475:89-95

The adsorption geometry of Ag(1 1 1)–(√7×√7) R 19.1°-4Ar was studied using low-energy electron diffraction (LEED). This higher-order commensurate phase was produced by preadsorbing a small amount of CO in order to block the close-packed steps

Low-energy electron diffraction study of the surface geometry of Ni(100)–(3×3)-K+4O

Autor: M. Caragiu, Matti Lindroos, Ronan McGrath, P. Finetti, Renee D. Diehl, G. S. Leatherman

Publikováno v: Surface Science. 462:77-84

A dynamical LEED study of the (3×3) structure which forms upon coadsorption of K and O on Ni(100) indicates that this structure is comprised of one K atom and four O atoms per (3×3) unit cell. The K atom is adsorbed in a substitutional site, and su
