Pyroelectric properties of RbHSeO₄crystals

Investigations on the SR method growth, etching, birefringence, laser damage threshold and dielectric characterization of sodium acid phthalate single crystals

“…The dielectric and ferroelectric properties of SEST grown NaAP were investigated [11]. Its pyroelectric properties were measured by Poprawski et al [12] and low-frequency Raman and infrared spectra by Miniewicz et al [13]. Its elastic properties were investigated by Ecolivet et al [14] and electro-optic properties were measured by Miniewicz and Bartkiewicz [15].…”

Correlation between dielectric and electro-optic properties related to domain dynamics inRbHSeO4crystals

“…This crystal is known as a hydrogen-bonded ferroelectric with the Curie point at 371 K. 4 At room temperature RHSe presents the triclinic symmetry P1 and possesses ferroelastic, pyroelectric, and ferroelectric properties that have been widely studied. [5][6][7] Below T C , the crystal always exhibits a layered domain structure with walls parallel to the (a,b) crystallographic planes, and the spontaneous polarization directed close to the b axis. Neighboring domains are each other symmetrical by a twofold rotation around the axis perpendicular to the (a,b) planes.…”
