Abstract
The trigonal lithium niobate crystal (LiNbO3, LN) is a multi-functional material, which possesses excellent pyroelectric and piezoelectric properties as well as the nonlinear optical properties etc. In this paper, the stability of electro-elastic properties of LN crystal irradiated by the 6MeV Xe23+ ions were evaluated for potential piezoelectric applications in harsh environment. the electrical resistivity of the irradiated LN was found to decrease with increasing irradiation dose. In contrast to the electrical resistivity, the relative dielectric permittivity ε22/ε0 of LN sample was found to increase with increasing irradiation dose. The values of electromechanical coupling factor k21, the elastic compliance s11 and the piezoelectric coefficient d21 for the irradiated samples were determined and found that the irradiated LN crystal could maintain its electro-elastic properties similar to the pristine crystal.
