Figure 1

The typical load-displacement (P-h) curve for (a) elastic and (b) viscoelastic material; (c) the elastic interaction volume within an elastic material with its size l1 correlated with the elastic properties and AFM tip radius; and (d) the elastic interaction volume within a viscoelastic material with its size l2 correlated with the viscoelastic properties and AFM tip radius. Note that, if all conditions remain identical except the presence of liquid-like regions, l2 should be smaller than l1 because of the energy dissipation.
