| Abstract: | We investigated defect formation within nanostructured materials using a transmission electron microscope (TEM) and ion accelerators. Controlling diffusion coefficient of the defects we have first observed changes in pattern of defect clusters, namely, the diffusion-limited reaction of defects in nanocrystals.
