Abstract:
Lithium niobate is a ferroelectric material suitable for a variety of applications. Its versatility is made possible by the excellent electro-optic, nonlinear, and piezoelectric properties of the intrinsic material. It is also used as a substrate for crystal growth, so it is very important to know the response of the material to the applied electric field.The dielectric and optical properties of lithium niobate single crystal were tested, and the effects of different effective voltages on dielectric permittivity, dielectric loss and conductivity were analyzed. The frequency dependence of the dielectric permittivity, dielectric loss, and ac conductivity have been examined in frequency (20 Hz–200 kHz) range. The optical properties were studied on the basis of the absorption spectra in the UV-Vis region.
