  • Method of obtaining a ternary monocrystalline layer by means of hetero-epitaxy on a binary layer and a crucible suitable for putting the method into effect
    Patent number: 5064780
    Abstract: The invention relates to a method of obtaining by heteroepitaxy a monocrystalline layer of a ternary compound on a monocrystalline substrate of a binary composition, in which a saturated solution (A) of the ternary compound is brought into contact with the substrate (90), the assembly being raised to a first temperature, and is thereafter cooled to a second temperature.The dynamics of the epitaxial growth is improved in accordance with the invention by placing the substrate (90) on the surface of the solution (A).
