Abstract

The primary and secondary pyroelectric coefficients were determined for binary (1-x)Pb(Mg_1/3Nb_2/3)O₃-xPbTiO₃ (PMN-PT) and ternary Pb(In_1/2Nb_1/2)O₃- Pb(Mg_1/3Nb_2/3)O₃-xPbTiO₃ (PIN-PMN-PT) relaxor-PT single crystals. The secondary pyroelectric coefficients were calculated from the thermodynamic inter-relationship between the piezoelectric, elastic, and thermal expansion coefficients. Poling along [111] and [001] directions resulted in single-domain state of "1R" and "1T" and a macroscopic symmetry of 3m and 4mm for rhombohedral (x = 0.28) and tetragonal (x = 0.42) crystals, respectively, enabling relatively large values of pyroelectric coefficients p ≥ 5.7 × 10^-4 C/m² K. The calculated results show that the secondary pyroelectric coefficients are in the range of (-0.62 ∼ -1.06) × 10^-4 C/m² K for rhombohedral crystals and (0.70 ∼ 1.14) × 10^-4 C/m² K for tetragonal crystals, significantly lower than that of primary pyroelectric coefficients, which is important for thermal directional and imaging applications. In contrast, high d₁₅ piezoelectric coefficients (>2000 pC/N), together with zero pyroelectric coefficients in thickness shear crystals, also makes them promising candidates for piezoelectric sensors where thermal noise is undesirable.
