铁电畴的普适性质

Universal Properties of Ferroelectric Domains

Igor A. Lukyanchuk, Laurent Lahoche, Anais Sene

摘要:

基于Ginzburg-Landau方法,我们推广了Kittel理论,导出了多畴极化剖面P(x,z)的温度演化插值公式。我们解决了长期存在的问题,近表面的铁电畴的极化行为,并证明了极化消失,而不是通常假设的分形域分支。我们提出了一个有效的缩放方法来比较不同的域包含铁电板和薄膜的性能。

英文摘要:

Basing on Ginzburg-Landau approach we generalize the Kittel theory and derive the interpolation formula for the temperature evolution of a multi-domain polarization profile P(x,z). We resolve the long-standing problem of the near-surface polarization behavior in ferroelectric domains and demonstrate the polarization vanishing instead of usually assumed fractal domain branching. We propose an effective scaling approach to compare the properties of different domain-containing ferroelectric plates and films.
