Copper substrate texture

As will be discussed in Chapter 17, the specific texture of the copper substrate on which a nanomultilayer system such as, say, Cu/Ni layer pairs is deposited has direct bearing on the system s texture and consequently magnetic characteristics. 

It is obvious from simple geometrical considerations that in any process for applying molybdenum disulphide to a solid substrate, the first contact is likely to be at the peaks of the asperities on the substrate. However, Johnston and Moore were the first to study the burnishing process in detail, using a cylinder covered with fabric to apply molybdenum disulphide powder to a flat copper substrate. They found that in their tests the first hundred traverses of the burnishing device filled the low spots on the substrate so as to produce a smooth surface. Subsequent traverses built up further layers of molybdenum disulphide onto the film, and the film thickness appeared to increase indefinitely without any significant subsequent change in the texture of the surface.

Seiter et al. (40) found a correlation between overpotential tj and growth forms of electrodeposited copper on copper sheet substrate with (fOO) texture, shown in Figure 7.18. 

Seiter et al. [80] found a correlation between the overpotential and growth forms of electrodeposited copper on copper sheet substrate with (100) texture, as shown in Fig. 31. Barnes etal. [81] observed similar results on copper single crystal surfaces near (100) face below 10-mV ridges, 40-70-mV platelets, 70-100-mV blocks and fine platelets and above 100-mV polycrystalline deposit. 

A second example of the application of laser ablation was reported by Chmielowska et al. [260]. The authors carried out structural analysis of thin cerium dioxide films doped with copper, which were produced for applications as catalytic gas sensors. The thin films deposited on a silicon substrate had a nanocrystalline structure with a well-developed texture. The morphology, as well as the preferred orientation of the films, changed with the volume fraction of copper. The observed variations were found to affect the catalytic properties of the materials.
