Figure 10.

Illustration of realizations of noise-contaminated indentation data with noise amplitudes ${\eta }_{\mathrm{h}}=0.01$, ${\eta }_{\mathrm{s}}=0.01$, ${\eta }_{\mathrm{h}}=0.10$ and ${\eta }_{\mathrm{s}}=0.10$ superposed on the indentation data for Se. (a) Normalized indentation depth $h/h_{\mathrm{ela}}$ versus normalized time $t/t_{\mathrm{ref}}$. (b) Surface profiles near the indenter after unloading. (c) ${\log }_{10}$–${\log }_{10}$ plot of (a).
