“…These compare favorably to the respective, room temperature values of 300 C m −2 K −1 and 190 C m −2 K −1 for two useful pyroelectric materials, triglycine sulfate (TGS) and lithium tantalate (LiTaO 3 ). 17 For the LTFH poled crystals of PMN-28PT and PMN-33PT (Table II) the pyroelectric coefficients increased in the order predicted by a pseudorhombohedral symmetry and agree well with the analysis of the dielectric data. The highest value of p * observed, 1071 C m −2 K −1 , was measured in the ͓111͔ C samples of PMN-28PT, corresponding to the rhombohedral polar axis.…”

The pyroelectric coefficients of 0.72Pb(Mg1∕3Nb2∕3)O3-0.28PbTiO3 (PMN-28PT), 0.67Pb(Mg1∕3Nb2∕3)O3-0.33PbTiO3 (PMN-33PT), and 0.92Pb(Zn1∕3Nb2∕3)O3-0.08PbTiO3 (PZN-8PT) single crystals, oriented and poled along three different crystallographic directions, [001]C, [011]C, and [111]C, have been measured using a dynamic method. The suffix C indicates reference to the prototypic cubic coordinate system. Large coefficients of up to 1070μCm−2K−1 have been observed for the [111]C oriented, rhombohedral PMN-28PT and PMN-33PT samples, where the measurement direction corresponds to the polar axis of the crystal. For each composition and orientation two different poling procedures are compared, a commonly used field cooling method and a low temperature poling protocol. It was found that in otherwise pseudoorthorhombic samples of PZN-8PT, a room temperature rhombohedral phase could be stabilized by application of a field along the [111]C direction while heating from −70°C.

“…In fact, there are numerous literatures about infrared (IR) thermal detectors based on all kinds of pyroelectric materials such as lead zirconate titanate (PZT), triglycine sulfate (TGS), barium strontium titanate (BST) and lithium tantalate (LT) [9][10][11][12][13]. However, there are few reports on the application of pyroelectric devices in the field of THz detection and imaging [14].…”

Two samples of 30-pixel linear terahertz detector arrays (TDAs) were fabricated based on lithium tantalate (LT) crystals. Pixel readout circuit (ROC) was designed to extract the weak current signal of TDAs. A test platform was established for performance evaluation of TDA+ROC components. By using a 2.52THz laser as radiation source, the test results reveal that average voltage responsivities of the components were larger than 7000V/W and non-uniformity no more than 2.1%. Average noise equivalent power (NEP) of one sample was measured to be 1.5×10 -9 W/Hz 1/2 , which is low enough and desirable for high performance THz detector.
