Fitting analysis of the intensity profile in the soft X-ray images. The F Kα image at the CF-matrix/adhesive interface region and the fitting analysis of the N and F Kα intensity profiles at the positions of (i), (ii), (iii), and (iv). The N and F Kα intensity profiles were analyzed using Boltzmann and Gaussian functions, respectively. The best fit results are indicated by the thick solid curve. The FWHM of the best fit curve is provided in each figure. The triangle (i), diamond (ii), square (iii), and circle (iv) data points correspond to the symbols used in Fig. 4.
