铌相畴的布拉格投影重叠关联成像
Bragg projection ptychography on niobium phase domain
摘要：
我们证明了布拉格相干衍射测量的高灵敏度相衬特性结合的平移的多样性的重叠，可以提供一个布拉格“暗场”成像方法能够揭示在金属薄膜中的域结构的指纹。实验衍射数据取自蓝宝石上外延生长的铌金属薄膜，并与实施细化机制的仔细组合的帮助下进行分析。
英文摘要：
We demonstrate that the highly sensitive phase-contrast properties of Bragg coherent diffraction measurements combined with the translational diversity of ptychography can provide a Bragg "dark field" imaging method capable of revealing the finger print of domain structure in metallic thin films. Experimental diffraction data was taken from a epitaxially grown niobium metallic thin film on sapphire; and analysed with the help of a careful combination of implemented refinement mechanisms.
