摘要：LiInS_2 is known as a multi-functional noncentrosymmetric (NCS) crystal. LiInS_2 crystal with diameter of 12 mm was successfully grown by the modified Bridgman method. We report the full set of elastic, dielectric and piezoelectric constants of LiInS_2 crystal by resonance technique and impedance analysis. Our results indicate that the LiInS_2 crystal has good piezoelectric properties (d_(24)=-13.3 pC/N, d_(33) = 9.6 pC/N). The origin of the piezoelectric properties of LiInS_2 crystal is analyzed based on the crystallographic aspect of its polar structure. It is found that the elastic constants s_(44) and s_(66) of the LiInS_2 crystals have slight variations with temperature. The results suggest that the LilnS_2 crystal is a promising candidate for piezoelectric applications.
