While bulk crystalline elemental metals cannot be amorphized by ion irradiation in the absence of
chemical impurities, the authors demonstrate that finite-size effects enable the amorphization of
embedded Cu nanocrystals. The authors form and compare the atomic-scale structure of the
polycrystalline, nanocrystalline, and amorphous phases, present an explanation for the extreme
sensitivity to irradiation exhibited by nanocrystals, and show that low-temperature annealing is
sufficient to...[Show more]
