Cross-sectional STEM image of the a pristine FeGe film and b film irradiated with 1013 ions/cm2. Dashed square encloses an irradiation-induced amorphous region and the solid square encompasses an example of a crystalline region. Scale bars are 5 nm. c EELS measurement of the FeGe film irradiated with 1013 ions/cm2. Solid lines show signal intensity for each element; the signal is smoothed using a third-order Savitzky-Golay filter.
