Self-diffusion can occur in solids, liquids, and gases, but is most commonly observed in solids. It is a fundamental process in materials science and is important in understanding various phenomena such as crystal growth, phase transformations, and diffusion-controlled reactions. The rate of self-diffusion is influenced by factors such as temperature, crystal structure, and the presence of impurities or defects in the crystal lattice.
