МОНОКРИСТАЛЛ СО СТРУКТУРОЙ ГАЛЛОГЕРМАНАТА КАЛЬЦИЯ ДЛЯ ИЗГОТОВЛЕНИЯ ДИСКОВ В УСТРОЙСТВАХ НА ПОВЕРХНОСТНО-АКУСТИЧЕСКИХ ВОЛНАХ И СПОСОБ ЕГО ПОЛУЧЕНИЯ

摘要

FIELD: production of acoustic electronic frequency-selective units on acoustic surface waves. ^ SUBSTANCE: used as monocrystal with calcium gallogermanate structures in units on surface acoustic waves is monocrystal whose geometric axis is perpendicular to thermostable shear; such monocrystal is grown by Chohralsky method with seed crystal oriented in direction perpendicular to thermostable shear. Proposed monocrystal increases number of disks up to 80% fully free from growth defects-gas bubbles. ^ EFFECT: enhanced efficiency; possibility of obtaining growth defects-gas bubbles. ^ 3 cl, 2 dwg, 3 ex
