Fitting of x-ray reflectivity data — GenX 3.7.9 documentation
During the fit there are mainly three different tabs that are interesting. Firstly, the data tab that shows the data and model, the most understandable plot. Secondly, the FOM folder this shows the Figure of Merit as a function of the generations (iterations). When this has flattened out there will be little improvement of the fit.
从理论到实践,一文搞懂X射线反射率 (XRR) - Westlake
2023年12月11日 · X射线反射率(X-ray reflectivity,XRR)是一种分析薄膜厚度、粗糙度、密度的表面分析方法。 XRR的基本原理是利用X射线在薄膜表面及界面的反射及折射光的相互干涉,它和我们了解的XRD的衍射原理无关,因此XRR不止可以分析结晶薄膜,也可以分析无定形薄膜。
