Understanding and controlling how the diffusion process works at the atomic scale is an important question in the synthesis of materials. For nanoparticles, the stability, size, structure, composition, and atomic ordering are all dependent on position inside the particle, and diffusion both affects all of these properties and is affected by them. A more thorough understanding of the mechanisms and effects of diffusion in nanocrystals will help to develop controlled synthesis methods to obtain the particular properties; however, conventional methods for studying diffusion in solids all have limitations.
