Stable reconstruction of the polar (111) surface of NiO on Au(111)

Physical Review B, 1994
Several theoretical studies of the stability of (111)-terminated ionic crystals with the NaCl structure have predicted that the crystal Madelung energy can be stabilized by a simple surface reconstruction. However, previous attempts to grow (111)-terminated crystals have resulted in either unreconstructed or faceted surfaces.

Adsorption Site Determination for Au-Octanethiolate on Au(111)

Langmuir, 2010
Self-assembled monolayers (SAMs) of Au-octanethiolate on Au(111) have been studied using scanning tunneling microscopy (STM). Thermal annealing of the dense (square root(3) x square root(3))R30 degrees layer at 353 K for 1 h leads to the formation of a (5 square root(3) x square root(3))R30 degrees striped phase coexisting with the (square root(3) x ...

Acoustic Plasmon on the Au(111) Surface

Physical Review Letters, 2010
We report an acoustic surface plasmon mode on the Au(111) surface, which disperses into the visible region, as measured by high resolution electron energy loss spectroscopy. The new mode is assigned to an acoustic surface plasmon arising from the Shockley-type surface state electrons and coexists with the conventional surface plasmon.

Surface melting behaviour of Au(111)

Surface Science Letters, 1987
The melting behaviour of a metal surface is of considerable experimental interest, but has not so far been studied theoretically at a quantitative level. We have undertake a molecular dynamics study of Au(111) based on the empirical but thoroughly tested “glue” many-body force scheme.

Polymerization at the Alkylthiolate−Au(111) Interface

The Journal of Physical Chemistry B, 2007
The density functional theory is used to explore alkylthiolates (RS) bonded to Au(111) and gold adatoms on Au(111). Adsorption of RS to adatoms in a structure characterized as an (RSAu)x polymer is strongly preferred over terrace adsorption. The energetic gain upon polymerization is large enough to drive the required Au(111) reconstruction. The results

Faceting and reconstruction of stepped Au(111)

Physical Review B, 1995
We present the results of an x-ray scattering study of the structure and morphology of a stepped Au(111) surface between 480 and 1225 K. At the highest temperatures studied, the surface phase separates to form three distinct orientational phases, each of which is reconstructed.

Growth of Au on A Ge (111) Surface

MRS Proceedings, 1991
ABSTRACTWe investigate the room temperature growth of evaporated Au thin films on both clean and dirty single crystal Ge (111) substrates. The annealing behavior of these films was then examined under low and high temperatures.

Dipoles and band alignment for benzene/Au(111) and C60/Au(111) interfaces

Applied Physics A, 2009
A local orbital DFT-approach combined with a “scissor”-operator is used to obtain the Charge Neutrality Level and the screening parameter in the benzene/Au(111) and C60/Au(111) interfaces. The “pillow” dipole and interface Fermi level are also calculated.

Adsorptive Behavior of Dimethylglyoxime on Au(111)

Langmuir, 2011
Dimethylglyoxime (DMG) adsorbed on Au(111) was investigated using electrochemical scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). STM experiments revealed three different structures of adsorbed DMG at open circuit potential (~0.07 V versus Ag/AgCl): (2√3×2√3)R30°-α, (2√3×4√3)R30°-β, and (2√3×4√3)R30°-γ.

Adsorption of Carbohydrazide on Au(111) and Au3Ni(111) Surfaces

Catalysis Letters, 2018
Carbohydrazide (CH6N4O) is a potential substitute to hydrazine in fuel cell applications. This paper presents a theoretical study on the adsorption of carbohydrazide on Au(111) and Au3Ni(111) surfaces using first principles calculations based on density functional theory.
