Abstract

Piezoelectric and pyroelectric properties as well as strain behavior of 0.5 mol% Mn-doped 0.36Pb(In1/2Nb1/2)O3-0.36Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 (Mn-PIMNT) ceramics were studied. High piezoelectric coefficient of d33 = 235 pC/N, planar electromechanical coupling factor of kp = 43.1% and the high-power Figure of Merit (FOM = 60160 pC/N) were achieved in Mn-PIMNT ceramics. Furthermore, the ceramics exhibited high pyroelectric coefficient of p = 4.8×10-4 Cm-2 K-1 , figures of merit for the current responsivity of Fi = 1.92×10-10 mV-1 , the voltage responsivity of Fv = 0.028 m 2 C-1 , and the detectivity of Fd = 2.317×10-5 Pa-1/2 at room temperature. The excellent piezoelectric and pyroelectric properties together with high ferroelectric rhombohedral to tetragonal phase transition temperature of Trt = 146 ℃ and ferroelectric tetragonal to cubic phase transition temperature of TC = 188 ℃ make the Mn-PIMNT ceramics suitable for high-temperature piezoelectric and pyroelectric devices.

“…0.5 mol% Mn-doped Mn-PIMNT(36/36/28) ceramic targets were fabricated by a conventional solid-state reaction technique. 20 The conductive oxide SrRuO 3 (SRO) thin film was deposited on (111)-oriented SrTiO 3 (STO) single-crystal substrates by pulsed laser deposition (PLD) using a krypton fluoride (KrF) excimer laser with a wavelength of 248 nm. Then, Mn-PIMNT(36/36/28) thin films were deposited on SRO-buffered (111)-oriented STO substrates and the deposition conditions of SRO and Mn-PIMNT(36/36/28) thin films are listed in Table 1.…”

Growth of the ternary Pb(Mn,Nb)O3–Pb(Zr,Ti)O3 thin film with high piezoelectric coefficient on Si by RF sputtering

“…Recent studies indicated that ternary relaxor ferroelectric systems represented by Pb(In 1/2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PIMNT) and Pb(Mn 1/3 Nb 2/3 )-PbZrO 3 -PbTiO 3 were developed to simultaneously possess electromechanical properties and stable piezoelectric response. [13][14][15][16] Among them, the 0.06 Pb(Mn 1/3 Nb 2/3 )-0.94 Pb(Zr 0.48 Ti 0.52 )O 3 (PMN-PZT) aroused extensive attention due to the superior electromechanical properties as the composition was close to the MPB between rhombohedral (R) and tetragonal (T) phases. 17 High-quality PMN-PZT thin film was also developed on Pt-electrode MgO substrate with high ferroelectric polarization up to 100 μC/cm 2 and high Curie point.…”
