On the Tapping Mode Measurement for Young’s Modulus of Nanocrystalline Metal Coatings

Figure 5

The measured 𝛼 value (𝑠) that corresponds with the square root of the slope in region 3′′ (of Figure 1) is plotted as function of the reduced modulus 𝐸^∗ value for various sample materials where the crystalline orientation is indicated by the symbol shape in the legend.
