METHOD AND APPARATUS FOR GROWING MONOCRYSTALS FROM VAPOR PHASE Russian patent published in 1995 - IPC

FIELD: production of materials used in electronic equipment and quantum electronics. SUBSTANCE: method involves placing basic materials and monocrystalline seed into growing ampoule; heating basic materials to temperature exceeding that of seed; positioning at least one forming member, heated to temperature exceeding that of seed in the vicinity of seed surface to modify temperature field adjacent to seed surface; moving seed with growing monocrystal relative to forming member in the process of growing. Apparatus is characterized in that the profile of forming member surface is made in conformity with profile of surface of monocrystal to be grown. Holder where seed is positioned, is provided with controllable drive for moving seed relative to forming member. EFFECT: increased quality of monocrystals, provision for predetermined configuration of growing surface and cross-section and increased size of monocrystals. 14 cl, 10 dwg, 1 tbl
