Abstract ：
Electronic, elastic and piezoelectric properties of two-dimensional (2D) group-IV buckled monolayers (GeSi, SnSi and SnGe) are studied by first principle calculations. According to our calculations, SnSi and SnGe are good 2D piezoelectric materials with large piezoelectric coefficients. The values of d(11) of SnSi and SnGe are 5.04 pm/V and 5.42 pm/V, respectively, which are much larger than 2D MoS2 (3.6 pm/V) and are comparable with some frequently used bulk materials (e.g., wurtzite AlN 5.1 pm/V). Charge transfer is calculated by the Lowdin analysis and we find that the piezoelectric coefficients (d(11) and d(31)) are highly dependent on the polarizabilities of the anions and cations in group-IV monolayers.

Abstract ：
In this work, 9BZT-BT ceramic has been studied by both experiment and theoretical ab initio molecular dynamics. In experiment, there are two sets of polar regions with different decay temperatures coexisting in the sample. With increasing temperature, one set gradually decomposes between -45 and -15 degrees C, whereas the other set keeps stable until much higher temperatures. Ab initio molecular dynamics simulations show that Bi3+-Zn2+ displacement coupling plays a crucial role at high temperatures to stabilize the micro-domains and ergodic state polar nanoregions (PNRs). This mechanism could be used to explain the complex polarization behaviors and strong relaxor phenomenon observed in experiment. (C) 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Abstract ：
Bi-2((Zn1/3Nb2/3)(1-x)Ti-x)(2)O-7 ceramics with 0 <= x <= 0.4 were synthesized using solid-state reaction method. The crystal structure is pure zirconolite type for the compositions with 0 <= x <= 0.15, single weberite type for the compositions with 0.3 <= x <= 0.4, and mixture of zirconolite and weberite for the compositions with 0.15 < x < 0.3. The weberite ceramics with only Bi as the A-site cation are first reported. A possible correlation between the crystal structure transformation and Ti content in system of Bi-2((Zn1/3Nb2/3)(1-x)Ti-x)(2)O-7 with 0 <= x <= 0.4 was suggested. Dielectric constant (e), dielectric loss (tan delta) and temperature coefficient of capacitance (TCC) are similar to 85, similar to 0.001, and similar to 200 ppm/degrees C for the zirconolite solid solutions, similar to 140, 0.004, and between -120 and similar to 200 ppm/degrees C for the weberite solid solutions, respectively, at 1 MHz. Ceramics with a near zero TCC consisting of the zirconolite and weberite phases were obtained. High epsilon, low tan delta, and low sintering temperatures (similar to 950 degrees C) make the novel ceramic system of Bi-2((Zn1/3Nb2/3)(1-x)Ti-x)(2)O-7 potential dielectrics for applications in low-temperature co-fired ceramic and multiplayer ceramic capacitors.

Abstract ：
This paper describes an automated-measurement system of ferroelectric hysteresis loops, which was developed in LabView environment based on Virtual Instrument. The system provides a function obtaining nonlinear polarization current from measured current data, which is important for properly estimating ferroelectricity of a dielectric, especially for one with high electric loss. In addition, the relationship between nonlinear polarization current density and external electric field of a ferroelectric reveals more information which is helpful for researches of polar order and/or ferroelectric characteristics.

Abstract ：
(BixBa1-x)(Znx/2Ti1-x/2)O-3 [xBi(Zn1/2Ti1/2)O-3-(1-x)BaTiO3, x <= 0.30] solid solution ceramics with a pure perovskite structure were synthesized by a conventional solid-state reaction method. A change in symmetry from tetragonal to cubic was observed as the mole fraction of Bi(Zn1/2Ti1/2)O-3 increased. All compositions show a dielectric anomaly over the temperature range 30-120 degrees C. In the tetragonal phase region, the temperature Tm of the maximum dielectric constant decreases with increasing Bi(Zn1/2Ti1/2)O-3 content. In the cubic phase area, the compositions show general dielectric relaxation of linear dielectrics, and T-m increases with increasing Bi(Zn1/2Ti1/2)O-3 content. The phase transition, dielectric and ferroelectric properties of (BixBa1-x)(Znx/2Ti1-x/2)O-3 ceramics are sensitive to nano-regional chemistries.

Abstract ：
The ferroelectric hysteresis loops of Ba(Ti0.85Sn0.15)O-3 and Ba(Ti0.75Sn0.25)O-3 solid solution ceramics covering the temperature T-m of a dielectric permittivity peak were investigated. At temperatures similar to 100 K lower than their respective T-m, the two compositions present clear ferroelectricity. Comparing with the parent ferroelectric BaTiO3, the tiny hysteresis loop of both Ba(Ti0.85Sn0.15)O-3 and Ba(Ti0.75Sn0.25)O-3 ceramics at temperatures above T-m reveals the existence of polar order regions or microdomains. The dielectric properties of the two solid solutions are different: the former shows the character of diffuse ferroelectric phase transition, while the latter displays the feature of relaxor ferroelectrics. According to their ferroelectric properties, however, Ba(Ti0.85Sn0.15)O-3 and Ba(Ti0.75Sn0.25)O-3 compositions exhibit the diffuse transition from low-temperature ferroelectric domains to polar nanoregions during the epsilon(T) peak area. A difference between the two compositions is that the diffuse transition of the former takes place in a much narrower temperature range than that of the latter. (C) 2009 Elsevier Ltd.

采用传统陶瓷的制备方法,制备了(Ba1-xSrx/2Cax/2)TiO3(x=0.10,0.20,0.40,0.50,0.60)铁电陶瓷.X射线衍射分析表明:x=0.20时,陶瓷样品具有三方、四方共存的晶体结构.不同频率下陶瓷样品的介电温谱显示(Ba1-xSrx/2Cax/2)TiO3材料具有弥散相变的特征,在x=0.60时,(Ba1-xSrx/2Cax/2)TiO3陶瓷具有典型的弛豫铁电体特征.研究发现:当x=0.20时,(Ba1-xSrx/2·Cax/2)TiO3陶瓷材料的矫顽电场达到极小值.基于极性纳米微区理论的观点,进一步研究了弛豫铁电体和具有弥散相变铁电体两者之间的关系,结果表明:仅仅当实验频率和极性纳米微区的弛豫频率相近时,在弥散相变温区内介电弛豫行为才能被观察到.
