项目摘要

In this study, the patterning electrode was used to induce the finer engineered domain configurations with domain size of 3 pm. The poling treatment was performed at 134.0℃ under electric fields below 6 kV/cm to inhibit the burning of the patterning electrode with photoresist As the results, the gradient domain sizes from 3 to 8-9 pm were induced into the 31 resonator. Up to date, when the whole plane electrode was used, the minimum domain Ci7P was limited to 5 pm. However, using patterning electrode, the smaller domain size than 5 pm was successfully induced into the resonator. The chi was measured at -243.2 pC/N, and this value was almost 70% of the expected d31 of -337.7 pC/N for the resonator with domain size of 3 μm. This difference was originated from lower applied electric field below 6 kV/cm. This problem can be solved by development of the patterning electrode without photoresist. In the future, the developed patterning electrode with much finer pattern than 3 pm will be prepa … More red, and much higher d_31 will be challenged.Moreover, [110]-oriented Ba1103 ceramics were successfully prepared by the TGG method. It was revealed that the SaT103 ceramics had a high density of over 96% despite various Fm values. However; the average grain sizes were around 75 pm, and this size was too large compared with those (1.6-2.1 pm) reported by Takahashi, et al. and Karaki, et al. In the future, the grain ea should be below I pm for grain-oriented BaT103 ceramics. To achieve this, a new preparation method without using a template is required. In this study, BaTICI3 ceramics with a d_33 of 788 pC/N were first obtained. These ceramics had the engineered domain configuration with an average domain size of 800 run. This high domain wall density was the origin of the do higher than 500 pC/N. The most important point in this study is the confirmation that the structure gradient region such as the 90° domain wall region had an ultrahigh piezoelectric property intrinsically. This concept is universal, and can be applied to any ferroelectric materials. Using this concept, we can prepare ultrahigh-piezoelethric materials with a d_33 of 10,000 pC/N in the future. Less

在这项研究中，模式电子用于诱导域大小为3 pm的精细工程域配置。在低于6 kV/cm的电场下，在134.0℃进行poling处理，以抑制具有光蛋白天的图案电子的燃烧作为结果，将梯度域的大小从3到8-9 pm诱导到31个谐振器中。最新的，当使用整个平面电极时，最小域CI7P限制为下午5点。但是，使用图案电气，成功诱导了谐振器的较小域大小。 CHI以-243.2 PC/N测量，对于域大小为3μm的谐振器，该值几乎为-337.7 PC/N的预期D31的70％。该差异最初来自低于6 kV/cm的下施加电场。可以通过没有光震抗光抗命力的图案电气的开发来解决此问题。将来，预先准备的发达的图案电极要比下午3点要大得多……更红，更高的D_31将受到挑战。此外，[110]面向面向的BA1103陶瓷通过TGG方法成功制备。据显示，SAT103陶瓷的高密度超过96％，需要各种FM值。然而;平均谷物尺寸约为75 pm，与Takahashi等报道的（1.6-2.1 pm）相比，这种大小太大了。和Karaki等。将来，谷物EA应低于I pm，以供面向谷物的BAT103陶瓷。为此，需要一种新的准备方法，而无需使用模板。在这项研究中，首先获得了具有788 PC/N的D_33的Batici3陶瓷。这些陶瓷具有工程域的配置，平均域大小为800。这种高域壁密度是DO的起源高于500 pc/n。这项研究中最重要的一点是确认结构梯度区域（例如90°结构域壁区域）本质上具有超高压电特性。这个概念是普遍的，可以应用于任何铁电材料。使用这个概念，我们可以在将来使用10,000个PC/N的D_33进行超高pizoelethric材料。较少的
