    摘要： The present invention relates to a method for the production of crystal layers or bulk crystals of group III nitride or of mixtures of different group III nitrides by means of precipitation, at a first temperature T1 in a first temperature range, from a group-III containing fused metal on a group-III-nitride crystal seed placed in the fused metal or on a foreign substrate placed in the fused metal, with the admixture of nitrogen in the fused metal at a pressure P.With the method a solvent additive is added to the fused metal which increases the conversion rate of group III metal to group III nitride in the fused metal. The fused metal runs through at least one temperature cycle with a first and a second process phase in which cycle the fused metal cools after the first process phase from the first temperature to a second temperature T2 below the first temperature range and at the end of the second process phase is heated from the second temperature back to a temperature within the first temperature range. The described method permits producing group III nitride crystal layers with a thickness of >10 μm, respectively massive crystals with a diameter of >10 mm at dislocation densities of

    摘要： The invention relates to a device and a method for producing crystalline bodies by directional solidification. The device comprises a melting furnace (11) having a heating chamber (12) in which at least one supporting surface (13) for a crucible (8) and at least one gas purging device arranged above the supporting surface (13) and having a gas outlet facing the supporting surface (13) are defined. An embodiment of the device is characterized in that the gas outlet is defined by one or more openings in a lower plunger surface of a plunger-shaped element (2) which has a geometry adapted to the inner shape of the crucible (8), said shape allowing an at least partial insertion of the plunger-shaped body (2) into the crucible (8). The gas purging device and/or the supporting surface (13) comprise an adjusting mechanism or are designed to be adjustable in such a manner that they allow an adjustment of a perpendicular distance between the supporting surface (13) and the plunger-shaped body (2). The device and the corresponding method allow carbon- and oxygen-containing materials to be discharged from the melt more efficiently and in a controlled manner. The device and the method thus allow—within certain limits—a specific adjustment of the carbon and oxygen content of the crystalline bodies.
