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.
