Ordered Au Nanoparticle Array on Au(111) through Coverage Control of Precursor Metal−Organic Chains
(American Chemical Society, 2016-07)
Metal–organic overlayer structures formed by 1,4-phenylene-diisocyanide (PDI) and Au adatoms on Au(111) in UHV, their stability in air, and the tip-induced Au nanoparticle formation on PDI–Au(111) surfaces in air were ...
Comparative Study of the Adsorption of Thiols and Selenols on Au(111) and Au(100)
(American Chemical Society, 2017-12)
The effect of the Au crystalline plane on the adsorption of different thiols and selenols is studied via reductive desorption (RD) and X-ray photoelectron spectroscopy (XPS) measurements. Self-assembled monolayers (SAMs) ...
Theoretical study of Sn adsorbed on the Au(1 1 1) surface
(Elsevier, 2017-02-01)
In the present work, the adsorption of Sn atoms on the Au(1 1 1) surface was theoretically studied in the framework of density functional theory with a slab model. The results show that the most likely site for the adsorption ...
Estudio comparativo de la adsorción de S sobre Au(111) y Ag(111) con XPS, AES, TOF-DRS y LEED
(Asociación Física Argentina, 2014-08-14)
Here we study the adsorption of S on the (111) Surface of the noble metals Au and Ag using XPS, AES, LEED and TOF-DRS. Despite the similarities of the two surfaces, all the techniques showed different behaviours in both ...
Kinetics of low-temperature CO oxidation on Au(111)
(Elsevier Science, 2015-12-22)
The oxidation of carbon monoxide on oxygen-modified Au(111) surfaces is studied using a combination of reflection-absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD). TPD reveals that CO ...
Estados eletrônicos de superfície na face (111) do Au, Cu3Au e sulfeto sobre Cu3Au por espectroscopia de fotoelétrons resolvida em ângulo (ARPES)
(Universidade Federal de Minas GeraisBrasilICEX - INSTITUTO DE CIÊNCIAS EXATASPrograma de Pós-Graduação em FísicaUFMG, 2021-01-29)
This work seeks to deepen the knowledge about electronic states of surfaces (111) in noble metals such as Au and Cu3Au using, mainly, the ARPES technique (Angle-Resolved Photoelectron Spectroscopy) that allows to obtain ...
