论文摘要
具有高空间分辨率的X射线衍射是（Poly） - 晶体材料在微观或纳米镜尺度上表征的先决条件。这可以通过利用聚焦的X射线梁和样品扫描来实现。但是，由于X射线渗透到材料中，样品中衍射的确切位置是模棱两可的。在这里，我们利用数值模拟来计算空间分辨的衍射体积，以研究这些歧义。我们证明可以通过旋转样品来达到部分深度灵敏度。
X-ray diffraction with high spatial resolution is a prerequisite for the characterization of (poly)-crystalline materials on micro- or nanoscopic scales. This can be achieved by utilizing a focused X-ray beam and scanning of the sample. However, due to the penetration of the X-rays into the material, the exact location of diffraction within the sample is ambiguous. Here, we utilize numerical simulations to compute the spatially resolved diffraction volume in order to investigate these ambiguities. We demonstrate that partial depth sensitivity can be achieved by rotating the sample.
