The invention concerns a device () for forming in single-crystal state a compound body with incongruent evaporation, capable of being in monocrystalline or polycrystalline form, comprising at least one first chamber () containing a substrate () whereat is formed a polycrystalline source of said body and a monocrystalline germ () of said body; a second chamber (), said substrate being arranged between the two chambers; means for input () of gaseous precursors of said body into the second chamber capable of bringing about deposition of said body in polycrystalline form on the substrate; and heating means () for maintaining the substrate at a temperature higher than the temperature of the germ so as to bring about sublimation of the polycrystalline source and the deposition on the germ of said body in monocrystalline form.
