Very nice close up.

Andy Resnick said:Those are cool! Did that sample undergo any sort of annealing/dewetting/coarsening before the image was acquired? What's the significance of the rough texture (the fine scratchy-type features)?
Andy Resnick said:interesting... since there's a cut edge, have you taken a look at the cross-section, just for fun?
What device/system was used to obtain those images?ZapperZ said:Cu metals, especially thin-film deposited Cu, can be very smooth. However, the smoothness depends very much on the substrate and the type of deposition.
Here, Cu film was deposited using DC sputtering technique on Al2O3 (Alumina). I had the task of looking at the Cu-Al2O3 interface to see if they both bond to each other, and to look at the Cu surface. This is an SEM image of the Cu surface, showing the surface roughness. The surface is also a very disordered polycrystal.
