Top-seeded solution crystal growth of noncentrosymmetric and polar K3V5O14

Abstract

Large, centimetre-size crystals of the polar and noncentrosymmetric K₃V₅O₁₄ were successfully grown by a top-seeded solution growth (tssg) method. The morphologies of as-grown single crystals with different oriented seeds are described. The optical spectra indicate that its UV absorption edge is approximately 605 nm, and it has a transmission window to 5 μm. Piezoelectricity was also measured by the direct and converse methods. Finally, polarization properties were investigated on grown single crystals.
