Figure 6
(a)–(e) Histograms of generated currents from Fig. 4 : (a) control sample, (b) with 1% MACl, (c) 3% MACl, (d) 5% MACl and (e) 7% MACl. After the Gaussian deconvolution of peaks presented by orange (Peak 1, which is located closer to the average current values) and sky-blue lines (Peak 2, which is positioned further away from the average current values compared with Peak 1), a fitted curve (red line) could be obtained. The green line in each panel indicates average currents from the acquired XBIC maps. (f) Average current and occupied peak area, and (g) FWHM values regarding the concentration of additives acquired from (a)–(e) of Fig. 6 with Gaussian fitting. Additional values related to Gaussian fitting are placed in Table 3 . |
