CHAPTER 5

Diffusion

Atomic diffusion as introduced in this chapter involves individual atoms moving through crystal structures. In the high-resolution transmission electron micrograph on the left, we see a subtle image of one such atom in an interstitial position. The schematic illustration on the right shows this Ni atom to be in a silicon crystal as observed along the [110] direction, the same orientation shown in the Chapter Opening micrograph in Chapter 3.
