Abstract
Based on the relation between the structure and spontaneous polarization of TGS crystal, some modified TGS crystals have been grown by doping with aniline-family dipolar moleculars, inorganic acids and metal ions in the crystals. The effects of different dopants on growth habit and pyroelectric properties were investigated. The experimental results show that the pyroelectric figure of merit (p/e) of these new modified TGS-ATGSP and ATGSAs are one time higher than that of pure TGS crystal. The main approach of study on the modification of TGS crystal is also discussed in this paper.
