FIELD: construction.SUBSTANCE: electrodes in the form of a system of parallel strings are applied onto two flat-parallel faces of the crystal, which are aligned at the angle of z+36° to the polar axis, wire platinum contracts are connected to electrodes, the assembled cell is placed into a furnace and heated to temperature of phase transition - Curie temperature under action of a heterogeneous electric field, as a result of which two oppositely charged domains of equal volume are formed with a flat domain-to-domain border.EFFECT: invention makes it possible to change from traditionally used piezoceramic elements of deformation to single-crystal bidomain elements of precise positioning on the basis of single crystals of ferroelectrics with high Curie temperature, which do not have creep and hysteresis.2 cl, 2 dwg, 1 ex |
