Fig. 7

Electron beam-induced structure transformations in a single Co3O4 grain. a Indexed Fourier Transform of the [211] oriented grain of Fig. 6a. Note that the two image patterns A and B of Fig. 6a are hidden behind the same diffraction pattern. Line profiles are extracted along the dotted line. Note the significant broadening of the {022} and {044} diffraction spots if compared to the (4-4-4) diffraction spot, for example. b Line traces capturing the intensity of the indexed reflections of the Fourier transformed wave functions of Fig. 6a–c. Note the partial loss of intensity upon an increase of the dose rate
