Figure 4.1 shows the variation of pile-up height with indentation depth of the single crystal copper. The pile-up height of the single crystal copper shows a growth of approximate parabola with the increase of the indentation depth (from 300 to 800 nm), and the increase of amplitude is getting larger and larger. The pile-up heights change in the range of 45–95 nm, occupying the proportion of indentation depth about 12–15%.
