Hi..
Self diffusion is defined as the migration of constituent atoms within the bulk of a substance, especially in a crystalline solid where as vacancy diffusion refers to a diffusion process whereby the random thermally-activated movement of atoms in a solid results in the net transport of atoms.
Hope it helps u out..
