From: Ion irradiation induced phase transformation in gold nanocrystalline films
High-resolution microscopy before and after ion irradiation. Bright-field CTEM images from the same region of gold film (a) before and (b) after irradiation of 10 dpa. Green box in (a) denotes the region for the calculation of (c,e), and the red box in (b) denotes the region for the calculation of (d,f). (c) Fourier-transform calculated from the green box in panel (a). (d) Fourier-transform calculated from the red box in (b). (e) Bright-field atomic-resolution CTEM image from the green box in (a). The d-spacings of particular \(({{2\overline{2}0) }}\) and \(({{20\overline{2}) }}\) planes in FCC gold are labeled. (f) Bright-field atomic-resolution CTEM image from the red box in (a). The d-spacings of particular \(({{1\overline{1}00) }}\) and \(({{10\overline{1}0) }}\) planes in HCP gold are labeled.
