Dependence of interface roughness and diffuseness of Cu–Co electrodeposited multilayers on electrochemical additives

Abstract

We examine the effect of two organic additives, sds and saccharin, and also the effect of the solution pH on the interface properties of Cu/Co nanolayers, produced by pulsed electrodeposition from a single aqueous bath. Quantitative Fresnel fringe transmission electron microscopy is applied to cross-sectional samples of the layers. The widths of their respective interfaces as well as the widths of individual Cu and Co layers are determined via comparison with computer simulations. These initial results are further numerically treated to yield information about the separate contributions of interdiffusion and roughness to total interface widths. Conclusions on the behavior of these organic additives are considered in the light of the giant magnetoresistance properties of the multilayers, as reported in previous work.

Determination of Saccharin through a Carbon Paste Sensor Modified by Electrodeposition of Silver Film

“…The kinetics of saccharin degradation was also studied by voltammetry, 9 as well as the effect of the sweetener electrodeposition on metal alloys, such as CoFe, Ni-Zn and Cu/Co, which desirable effects such as wear resistance and reduction of alloy roughness were obtained. [22][23][24][25] This interfacial dynamical technique is capable of determining a targeted compound by monitoring its oxidationreduction processes by measuring the electric current as a function of the application of potential in a working electrode, obtaining voltammograms (current-potential curves). Voltammetry admits several techniques, such as cyclic voltammetry, in which the faradaic current is added to a capacitive and the initial potential is the same as the final.…”
