The smooth surface of large grains promotes specular scattering. In state-of-the-art microelectronics circuits, Cu interconnects are always used with a thin interlayer film between itself and the interlayer dielectric that serves as a Cu diffusion barrier, an adhesion promoter, and to arrest ...
The adsorption of dibenzyl disulfide (DBDS) on a Cu(111) surface model was investigated by using density functional (DFT) calculations, considering energetic and electronic aspects. Several complexes were generated, where the bridge, hollow hcp, hollow fcc and top adsorption sites were considered. ...
These yield a size insensitive work function, φ = 5.0±.1 eV, and a surface energy of 0.75 eV, in agreement with experiment. Good size convergence of the film potential permits the construction of a self-consistent potential for an 11-layer Cu(111) film, whose spectral properties we ...
Density functional theory (DFT) simulations were first carried out to elucidate the reaction mechanism of C2H2electroreduction on Cu. Herein, two types of surfaces were investigated: the Cu (111) surface representing the flat, nondefective surface and the stepped Cu (211) surface featuring undercoord...
We present results of an in situ STM study on the surface structure and anodic dissolution of Cu(111) electrodes in pure 0.01 M H2SO4 solution and in solution containing the corrosion inhibitor benzotriazole (BTAH), which is aimed at an atomistic understanding of the dissolution process and th...
(111) surface needs an activation energy of more than 1.4 eV (Fig.4b), and the O atom becomes stable only in the second subsurface interlayer space with a further energy barrier of 1.3 eV (Fig.4c). One of the main reasons for the strong resistance of a flat surface to oxidation...
A narrow peak close to the Fermi edge in photoemission spectra recorded normally to Cu(111) at high monolayer coverages of Na is explained in terms of one of a series of discrete states formed in the potential well between the Na vacuum barrier and the Cu(111) surface, which acts as a...
