Figure 3
A series of electron diffraction patterns taken from the same area at different dosages. Pattern (a) at beginning [same as Fig. 2[link](a)]; (b)–(d) after illumination at 100 pA cm−2 for an interval of 1 min between them; (e) after illumination at 100 pA cm−2 for 4 min; (f) after illumination at 500 pA cm−2 for 4 min; (g) after illumination at 500 pA cm−2 for 10 min. (h) The final image with nanopores after the boehmite to γ transformation and (i) intensity profiles of the patterns after background removal, showing the in situ transformation process by the e-beam irradiation.
