Growth and properties of metal-on-metal nanostructures: Ag on Cu(110) and Co on Ag(110)
… When Ag is deposited on clean, single-crystal Cu(110), it initially wets the surface with a (111) monolayer, and spontaneously nucleates nanowires as the coverage is increased. The nanowires nucleate at defects and step edges and grow aligned along the [1–10] direction. In the initial stages of …

First principles theory of organic molecules on metal surfaces : formate, 3-thiophene-carboxylate and glycinate on Cu(110)
We have performed ab initio calculations for the understanding of the interaction between organic molecules and the Cu(110) surface. We have used the program package EStCoMPP (Electronic Structure Code for Material Properties and Processes) that is based on density functional theory, …

RTM Untersuchungen an zweidimensionalen Nanostrukturen am Beispiel der reinen Au(100)-Oberfläche und des selbstassemblierten Systems Sauerstoff auf Cu(110)
… of the so-called (2x1) oxygen stripe phase on Cu(110) is imaged in situ, and simultaneously a quantitative determination of the induced surface stress is accomplished. The bending bar technique is utilized with the bending measured by the STM. Due to the anisotropy of the Cu(110) surface, two …

Surface reaction mechanisms as a function of surface composition, adsorbate coverage, and adsorbate acidity: I. Trimethylgallium on metal-treated silicon. II. Hexafluoropentanedione, methanol, and acetone on copper
… the reaction mechanism evolves from intramolecular decomposition, forming methane at very low coverage, to intermolecular interactions at half monolayer coverage, which form ethylene and facilitate methyl-gallium bond scission, to the desorption of gallium-alkyl species and methyl species at …

Applications of electron energy loss spectroscopies to the study of surface chemistry
… oxygen atom in NiO film grown on Ni(100) and Ni(110) surface and (2) nitrogen atom overlayer on Cu(100) and Cu(110) surfaces. EXELFS spectra obtained from the K-level of oxygen in NiO film grown on both the Ni(100) and Ni(110) surfaces reveal that the NiO films grown on both surfaces have the …

Atomistic simulation of deformation induced rotation in Cu-Nb composites
Accumulative roll bonding (ARB) of three copper-niobium (Cu-Nb) nano-composite models is simulated using molecular statics techniques to assess the rotational stability of Cu-Nb interfaces at high strains up to 90% thickness reduction. Crystals strain and rotate under compression, and certain Cu-Nb …

LEEDS studies of adsorbate-induced reconstruction of metal surfaces
… these surfaces are designated Ni(111)-(2x2)-0,Cu(110)-(2x3)-N, and Pd(100)-(V5x45)R27°-0. In each case, experimental data consist of a set of intensity-versus-energy (I(E)) curves measured at normal incidence with a video LEED analyser. Multiple-scattering calculations were done for a number of …

Systematic studies on structural and optical properties of organic thin films on inorganic substrates
Molecular organic compounds are employed as active materials in a variety of applications,including organic light emitting diodes (OLEDs) and organic thin film transistor (OTFTs). These devices consisting of sequentially deposited layers of organic materials have been demonstrated with active …

Investigation of the Surface-Electrolyte Interface of Semiconductors and Metals
This thesis focuses upon investigating the interface between semiconductors or metals with electrolyte. Understanding the interfacial dynamics are important to improving process performance, whether investigating photocatalytic systems or the nature of adsorption and reaction dynamics on metal …

Atomic and electronic structure of bulk intermetallic and heteroepitaxially grown surface alloys
It has been well documented that the surfaces of solids may differ from their bulk counterpart. The symmetry that a bulk possesses is broken at the surface. Due to this broken symmetry in the reduced dimension of the surface, the energetic of the surface also differs from the bulk counterpart. …
