چکیده
Aging rate (AR) of dielectric permittivity (ε33T/ε0) ternary Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PIN–PMN–xPT, x = 26 and 30 mol %) binary Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–xPT, single crystals (SCs) grown by the continuous-feeding Bridgman method (CF-BM) were investigated. The AR was 0.6–2.0 %/decade, whereas that loss SCs 1–8 %/decade. Even though SC growth methods different, CF-BM PMN–30PT similar with conventional one-charge (OC-BM) SCs. In this work, possessing high ε33T/ε0 more than 8000 alternating current poling (ACP) 4 to 7 times larger PZT ceramics. It is noted higher tend exhibit AR. Given in an unstable state within 10 h after poling, presented paper calculated from 100 poling. We hope work provides a new insight for evaluating properties addresses fact piezoelectric devices should be properly selected considering whether their could let them normally during entire lifetime.

Dielectric loss of SrTiO3 single crystals under direct current bias
The dielectric behavior of SrTiO3 single crystals under high dc electric field ~up to 50 kV/cm! is reported in this letter. The rounded dielectric constant peaks are induced by the application of dc bias, and the corresponding dielectric losses are observed. The results show that dielectric loss under dc bias consists of several components coming from ‘‘defects mode’’ and ‘‘induced mode.’’ The ...

متن کاملMeasurements of Relative Permittivity and Dielectric Loss Tangent of Fodel Dielectric with a Split-Post Resonator
The increasing use of computer-based software packages for designing RF/microwave circuits requires very accurate data about dielectric properties of materials used in the design. This paper presents results of precise measurements of relative permittivity and loss tangent of alumina substrates and Fodel dielectric 6050 used in thick-film photoimageable technology for fabricating microwave doub...
متن کاملPhotoluminescence characteristics of Cd1-xMnxTe single crystals grown by the vertical Bridgman method
In this paper, we report a systematic investigation of band-edge photoluminescence for Cd1-xMnxTe crystals grown by the vertical Bridgman method. The near-band-edge emissions of neutral acceptor-bound excitons (labeled as L1) were systematically investigated as a function of temperature and of alloy composition. The parameters that describe the temperature variation of the energy were evaluated...
