From: Ion irradiation induced phase transformation in gold nanocrystalline films
Microstructural evolution of the free-standing gold thin-film before and after ion irradiation. Bright-field CTEM image of the ROI in the gold film (a) before and (b) after ion irradiation of 10 dpa. Black arrow in (a) depicts the higher-magnification bright-field CTEM image of a grain boundary (c) before and (d) after ion irradiation of 10 dpa. Post-irradiation defects of stacking fault tetrahedra (SFT), defect clusters and voids are respectively labelled with yellow, blue and red arrows in (d).
