RESPONSE OF THE ATOMIC STRUCTURE OF COPPER SURFACES TO REACTANT MOLECULES AT AMBIENT PRESSURESEven the most compact and stable surfaces of Cu can undergornmassive reconstructions in the presence of reactant gases. Thernpristine surface consisting of atomically flat terraces separated byrnstep edges and...
Atomic Structure of Copper 2.3.2 Excitation and Atomic Transitions There are energy levels outside the valence shell to which electrons can be excited. Electrons that are excited to these levels will usually return to the lower energy state rapidly with the release of energy in the form of a ...
coppergrain boundary structureHRTEMThe atomic structure of an asymmetrical near 危 = 27 {525} tilt grain boundary (GB) in copper is determined by coupling high-resolution transmission electron microscopy and molecular dynamics simulation. The average GB plane is parallel to {414} in crystal (1) ...
The porous structure of E-FCOF-5 (f-up) and C-FCOF-5 (h-up). The single pts net of E-FCOF-5 (f-down) and C-FCOF-5 (h-down). Full size image For the contracted FCOF-5 (C-FCOF-5), the crystals were placed directly onto the copper grid without any dispersion. To ...
Size-selected copper nanolclusters for fabrication of isolated size-controlled nanostructures Here we report formation of isolated and mono-dispersed Copper islands of predicted size on Silicon substrate with native oxide and amorphous carbon film b...

In the present work, we investigated the atomic-scale manifestation of the Invar effect to lay grounds for its understanding in BMGs. Understanding the structure of metallic glasses is difficult due to their disordered atomic arrangement. One way to study structural rearrangements with increasing ...
The influence of grain boundary inclination on the structure and energy of σ = 3 grain boundaries in copper In a combined theoretical and experimental study, the energies and structures of σ = 3, [011] tilt boundaries in Cu were investigated. Equilibrium atomist... U Wolf,F Ernst,T Musch...
single-crystal CoO nanorods are in the oxygen vacancies that can be readily created on the oxygen-terminated {111} nanofacets, which favourably affect the electronic structure of CoO, assuring a rapid charge transfer and optimal adsorption energies for intermediates of oxygen reduction/evolution ...

It was also demonstrated that the ruthenium thin films prepared by ALD can be used as an excellent glue layer to improve the interfacial adhesion of metallorganic chemical vapor deposited copper to TiN. Secondary ion mass spectroscopy analysis showed that the ruthenium glue layer suppressed the ...
