论文摘要
尽管做出了多项努力，但仍存在许多与内部极化结构和铁电域壁相关相变的检测和分析相关的尚未解决的基本问题。他们的解决方案对于在高级记忆和其他信息技术中的域壁纳米电子学和相关应用中的进展可能非常重要。在这里，我们从理论上研究了域壁中相变的特征，这些特征可以通过扫描探针电容微波显微镜可以检测到。基于Landau-Ginzburg-Devonshire理论的有限元建模是针对与域壁运动相关的电容变化，以多轴铁电动batio $ _3 $。
Despite multiple efforts, there exist many unsolved fundamental problems related with detection and analysis of internal polarization structure and related phase transitions in ferroelectric domain walls. Their solution can be very important for the progress in domain wall nanoelectronics and related applications in advanced memories and other information technologies. Here, we theoretically study the features of phase transitions in the domain walls, which are potentially detectable by the scanning probe capacitance microwave microscopy. The finite element modelling based on the Landau-Ginzburg-Devonshire theory is performed for the capacitance changes related with the domain wall motion in a multiaxial ferroelectric BaTiO$_3$.
