“…MgSLN crystals could be prepared by double crucible Czochralski growth [3], vaportransport equilibration (VTE) [4], top-seeded solution growth with K 2 O as flux [5] or Czochralski growth from Li-rich melts with melt supplying technique [6]. Based on the substrate crystal produced by the above methods, a few exciting results about the study of the periodically poling of MgSLN were reported.…”

“…Cz method is the current mainstream technology for growing bulk LiNbO 3 single crystal [26][27][28]. With LiNbO 3 polycrystalline as starting materials, the Cz crystal growth is often controlled by the pulling/rotation rate and heater power [29,30]. The growth of LiNbO 3 crystal was affected by various factors together, such as the ratio of raw materials, quality of seed crystal, temperature gradient, growth parameters, etc.…”

“…A slower pulling rate is helpful to obtain a crystal with less internal stress and high quality. Table 1 shows pulling rate and rotation rate [26][27][28][29][30]. Recently, 6-inch LiNbO 3 crystals have been grown with a rotation rate of 5~10 rpm, and the pulling rate of 1-2 mm/h [26].…”

Lithium niobate (LiNbO3) crystals are important dielectric and ferroelectric materials, which are widely used in acoustics, optic, and optoelectrical devices. The physical and chemical properties of LiNbO3 are dependent on microstructures, defects, compositions, and dimensions. In this review, we first discussed the crystal and defect structures of LiNbO3, then the crystallization of LiNbO3 single crystal, and the measuring methods of Li content were introduced to reveal reason of growing congruent LiNbO3 and variable Li/Nb ratios. Afterwards, this review provides a summary about traditional and non-traditional applications of LiNbO3 crystals. The development of rare earth doped LiNbO3 used in illumination, and fluorescence temperature sensing was reviewed. In addition to radio-frequency applications, surface acoustic wave devices applied in high temperature sensor and solid-state physics were discussed. Thanks to its properties of spontaneous ferroelectric polarization, and high chemical stability, LiNbO3 crystals showed enhanced performances in photoelectric detection, electrocatalysis, and battery. Furthermore, domain engineering, memristors, sensors, and harvesters with the use of LiNbO3 crystals were formulated. The review is concluded with an outlook of challenges and potential payoff for finding novel LiNbO3 applications.

“…The Z-axis seed crystal was rotated at 10-30 rpm. Both the pulling rate of the crystal and the lowering rate of the mold were 0.2-1.5 mm/ h. Details of the growth technique are described elsewhere [8]. Z-cut 1-mm-thick wafers were cut from the top and bottom parts of each asgrown boule, respectively.…”

Uniform MgO-doped near-stoichiometric LiNbO(3) was successfully grown from Li-rich melts by a melt supplying technique. Periodically poled domains were demonstrated in MgO-doped near-stoichiometric LiNbO(3) wafers. Efficient quasi-phase-matched difference frequency generation was achieved in a titanium-diffusion waveguide based on periodically poled MgO-doped near-stoichiometric LiNbO(3). The conversion efficiency was -7.3 dB with a pump power of 150 mW and a signal power of 50 mW at room temperature. It was found that the 3 dB signal conversion bandwidth was as large as 78 nm. Photorefractive damage of the device was examined by pump-probe second-harmonic generation at room temperature, and the device exhibited no significant wavelength shift.
