Figure 4
XTG data obtained by scanning ΔtFF at Δtopt = 0 on SiC (a), SiO2 (b) and Si3N4 (c). The blue lines are Gaussian functions with FWHM as indicated in the figure. The experimental conditions are synthetically reported in the figure legend; the parameters that are not indicated are the same used in the case of diamond (see text). |
