An epitaxial growth of a first component of a multilayer stack for use in optical, electro-optical and electronic or magnetic components, e.g. on a silicon wafer, can be formed by depositing a second component in a form in which that second component produces a precipitate or inclusions in the first component which with continued deposition may be partly replaced by a third component so that the precipitate itself is buried in a monocrystalline structure and, after a thermal treatment in which the precipitate coalesces, a buried layer is formed of the second component or a compound thereof with, say, the first component, in that monocrystalline structure.
