Abstract

W jednym z rozwiązań przedmiotem wynalazku jest sposób otrzymywania objętościowego monokrystalicznego azotku zawierającego gal w środowisku nadkrytycznego rozpuszczalnika amoniakalnego z dodatkiem mineralizatora, polegający na tym, że w autoklawie wytwarza się nadkrytyczny rozpuszczalnik amoniakalny, zawierający co najmniej dwa rodzaje jonów metali alkalicznych (I grupa IUPAC 1989), korzystnie jony sodu i innego metalu alkalicznego, rozpuszcza się w tym rozpuszczalniku materiał źródłowy zawierający gal i prowadzi się krystalizację azotku zawierającego gal z nadkrytycznego roztworu na powierzchni zarodka w temperaturze wyższej i/lub ciśnieniu niższym niż dla rozpuszczania materiału źródłowego. Korzystnie jako mineralizator stosuje się sód w połączeniu z innymi metalami alkalicznymi, w stosunku molowym jonów sodu do innego metalu od 1:10 do 10:1. Sposobem według wynalazku otrzymuje się korzystnie azotek zawierający gal o wzorze ogólnym Al<sub>x</sub>Ga<sub>1-x</sub>N, gdzie 0<$E<<=>x<$E<<=>1.In one of the solutions, the subject of the invention is a method for obtaining bulk single-crystalline nitride containing gallium in the environment of a supercritical ammonia solvent with the addition of a mineralizer, consisting in the production of a supercritical ammonia solvent containing at least two types of alkali metal ions in an autoclave (IUPAC group 1989). , preferably sodium and other alkali metal ions, the gallium-containing source material is dissolved in this solvent and the gallium-containing nitride is crystallized from a supercritical solution on the surface of the seed at a temperature higher and/or a pressure lower than that for dissolving the source material. Preferably, sodium is used as a mineralizer in combination with other alkali metals, in a molar ratio of sodium ions to the other metal from 1:10 to 10:1. The method according to the invention preferably obtains a gallium-containing nitride with the general formula Al<sub>x</sub>Ga<sub>1-x</sub>N, where 0<$E<<=>x<$E<<= >1.
