WebFeb 1, 2024 · Topseeded solution growth (TSSG) is considered as a potential method for bulk growth of highquality SiC single crystals from the liquid phase source material. The crystal growth performance, such as growth rate and uniformity, is driven by the fluid flow and constitutional flux in the solution. WebJun 8, 2024 · The borate piezoelectric crystal Bi3TeBO9 (BTBO) was successfully grown by the top-seeded solution growth (TSSG) method. Frequency-dependent polarization measurements reveal that BTBO is not ferroelectric. Under the combined effects of high dielectric (ε33 = 62.60) and elastic constants (s33 = 15.33 pm2/N), BTBO exhibits a high …
