资源简介：
The complexity of ferroelectric domains presents a substantial challenge for characterization, especially with a non-destructive 3D probe. While Bragg Coherent Diffraction Imaging (BCDI) holds promise for this task, it still has some limitations. We have demonstrated that the Bragg Coherent Modulation Imaging (BCMI) technique is better suited for characterizing complex systems. This proposal aims to leverage the unique strengths of BCMI to investigate intricate ferroelectric domains, their dynamic behavior, and endurance during electric field cycling in BaTiO3 (BTO) nanocrystals of varying sizes.
铁电畴的复杂性为表征工作带来了严峻挑战，尤其是在采用非破坏性三维探针开展表征时。尽管布拉格相干衍射成像（Bragg Coherent Diffraction Imaging，BCDI）在该任务中具备应用前景，但仍存在一定局限性。我们已证实，布拉格相干调制成像（Bragg Coherent Modulation Imaging，BCMI）技术更适配复杂体系的表征需求。本研究提案旨在依托BCMI的独特优势，对不同尺寸钛酸钡（BaTiO3，BTO）纳米晶体中的复杂铁电畴、其动态行为以及电场循环过程中的耐久性能展开研究。
