Some Observations of Dislocation Etch Pits on {111} Surfaces of Cu and Cu-Al Dilute Alloy Crystals

TEXTURE AND RESISTIVITY OF Cu and DILUTE Cu ALLOY FILMS

Annealing of dilute binary Cu(Ti), Cu(In), Cu(Al), Cu(Sn), Cu(Mg), Cu(Nb), Cu(B), Cu(Co) and Cu(Ag) alloy films resulted in the strongest <111> fiber texture for Cu(Ti) and the lowest resistivity for Cu(Ag). The behavior of the alloy films was compared and contrasted with that for a pure evaporated Cu film. Electron beam evaporated films with compositions in the range of 2.0-4.2 at% and thickne...

Texture of Cu and Dilute Binary Cu-Alloy Films:

The impact of 11 alloying elements, namely Mg, Ti, In, Sn, Al, Ag, Co, Nb and B, at two nominal concentration of 1 and 3 at.%, and Ir and W, at only a nominal concentration of 3 at.%, on the evolution of texture of Cu was investigated. The behavior of the alloy films was compared with that for pure Cu films. The films were electron beam evaporated onto oxidized Si wafers and had thicknesses in ...

Probing enantioselectivity on chirally modified Cu(110), Cu(100), and Cu(111) surfaces.

Temperature programmed desorption methods have been used to probe the enantioselectivity of achiral Cu(100), Cu(110), and Cu(111) single crystal surfaces modified by chiral organic molecules including amino acids, alcohols, alkoxides, and amino-alcohols. The following combinations of chiral probes and chiral modifiers on Cu surfaces were included in this study: propylene oxide (PO) on L-alanine...

Accommodation and diffusion of Cu deposited on flat and stepped Cu(111) surfaces.

Cu AND DILUTE BINARY Cu(Ti), Cu(Sn) and Cu(Al) THIN FILMS: TEXTURE, GRAIN GROWTH AND RESISTIVITY

Annealing Cu and dilute Cu(Ti), Cu(Sn) and Cu(Al) alloy films resulted in the strengthening of film texture, with the strongest <111> fiber texture being found for Cu(Ti). Annealing also resulted in a decrease of electrical resistivity and the growth of grains, with the largest grain size and lowest resistivity being seen for pure Cu itself. Among the alloy films, the lowest resistivity was fou...
