“…An experimental study was conducted on the effect of gamma radiation and heat treatment on the optical properties of SbNbO 4 ferroelectric thin films. In addition, the structural and optical properties of the SbNbO 4 crystal were obtained experimentally (Mohamad et al, 1998 and2001). The dielectric and nonlinear optical properties of SbNbO 4 , SbTaO 4 , BiNbO 4 and BiTaO 4 crystals were obtained.…”

The structural, elastic, and piezoelectric properties of the NbSbO4 crystal were calculated based on the density functional theory. Calculations for these features were made using the ABINIT package program under the local density approximation. The elastic stiffness tensor and the elastic compliance tensor for the NbSbO4 crystal were calculated in the ground state. Voigt Bulk Modulus, Reuss Bulk Modulus, Hill Bulk Modulus, Voigt Shear Modulus, Reuss Shear Modulus, Hill Shear Modulus, Young Modulus, Poisson Ratio, Flexibility Coefficient, Debye temperature, Longitudinal sound wave velocity for NbSbO4 crystal using elastic stiffness and elastic compliance tensor, Transverse sound wave velocity and Average speed of sound were calculated. Then, the ground state piezoelectric tensor of the NbSbO4 crystal was calculated. accordingly, 2D longitudinal surfaces and 3D representation surfaces of the piezoelectric tensor were obtained using MTEX software.
