论文摘要
最近,我们发现,当传统的散装多晶压积盘(直径约10 mm)被稀释至厚度〜200微米或以下时,测得的单极电解质(UES)值显着增加(Arxiv:Arxiv:2208.07134)。在这里,我们证明这种异常现象与晶粒之间相互机械夹紧程度的降低密切相关,这又使铁弹性结构域的切换增强。
Recently we found that when conventional bulk polycrystalline piezoceramics discs (~ 10 mm diameter) are thinned down to thickness ~ 200 microns or below, the measured unipolar electrostrain (UES) values increased phenomenally (arXiv:2208.07134). Here we demonstrate that this anomalous phenomenon correlates strongly with the decrease in the degree of mutual mechanical clamping between the grains which in turn enables enhanced switching of the ferroelastic domains.
