  • size distribution extracted from TEM images (inset) from (a) bulk Ge-based CCA and (b) bulk Al-based CCA target. (a) Mn, Fe, Ni, Ge, and Si EDX elemental maps of the PLAL-generated CCA NPs from the bulk Ge-based CCA target. (b) Mn, Fe, Ni, Al, and Si EDX elemental maps of the PLAL generated CCA NPs
