Cu 2 O ( 1 1 0 ) formation on Co 3 O 4 ( 1 1 0 ) induced by copper impurity segregation

The surface crystal structure of the Co3O4(1 1 0) spinel was characterized by low energy electron diffraction (LEED), X-ray photoelectron spectroscopy (XPS), and Auger electron spectroscopy (AES). Well-defi ned LEED diffraction patterns showed an unreconstructed Co3O4(1 1 0) surface in Type A termination, and XPS and Auger indicated the surface to be stoichiometric with octahedral and tetrahedr...

Nonlinear Effects on Impurity Segregation in Edge Dislocation Strain Fields

Elastic field coupling to solute concentration is known to produce dislocationdriven impurity segregation. Recent reports detailing the distribution of boron around edge dislocations in B2-ordered FeAl indicate that nonlinear coupling of species concentration and elastic strain to the chemical potential must be considered to assess the magnitude of boron segregation around edge dislocations. On...

Comment on "Grain boundary decohesion by impurity segregation in a nickel-sulfur system".

Yamaguchi et al. (1) examined the embrittlement of nickel (Ni) by progressively adding sulfur (S) atoms to a grain boundary (GB). From first-principles calculations, they concluded that S atoms tend to aggregate at the GB and that the repulsive S-S interactions induce boundary expansion, thus weakening Ni-Ni binding across the boundary. The agreement between their calculated critical S concentr...

Formation of Cupric Oxide Films on Quartz Substrates by Annealing the Copper Films

In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...

Impurity Effects on the Recovery of Copper Studied by Ultrasonic Attenuation Measurements under Cyclic Bias Stress

High purity Cu single crystals doped with Mg, Ag, Pb, Sb, Bi (20-50 ppm) were isochronally annealed between 373 K and 923 K after 0.12% deformation at room temperature. After each annealing step the dependence of sound attenuation on frequency (10 200 MHz) and bias stress (cyclic compression/tension; peak amplitudes below plastic yield) was measured. From the latter experiment specific informat...
