X-ray reflectivity - Wikipedia
X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.

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。
X-ray reflectivity Fresnel reflectivity: • Simples case of reflection of x-rays from a single interface • Solve Helmholtz equation: propagation of light through medium characterized by refractive index Solution = plane wave: 𝐸 =𝐴 ⋅ − :𝜔𝑡−𝐤𝑗 ; Electro-magnetic field must be continuous at the interface!
Ki is the direction of incident X-ray, pointing to sample. The recorded image is the reflected beam intensity image. Two methods get the similar result for Sb deposition on Si (100).
An accurate X-ray reflectivity curve is defined by clear appearances of the total reflection critical angle, the period and the amplitudes of the oscillation.
X射线反射率(X-ray reflectivity, XRR)介绍及应用案例分享
2023年10月31日 · XRR是一种方便、快速的分析单层或多层薄膜和表面的方法，是一种纳米尺度上的分析方法，同时可实现无损分析。 例如，通过原子层沉积 (ALD)技术沉积的薄膜可以用XRR表征薄膜的厚度、密度和界面的粗糙度，同样也适用于其他方法制备的薄膜，如通过分子层沉积 (MLD)沉积的有机/无机超晶格。 与光学椭偏法不同，该方法不需要预先了解薄膜的光学性质，也不需要假设薄膜的光学性质。 然而，XRR不能提供有关材料晶体结构的信息，并且多层膜只能 …

What Is X-ray Reflectometry (XRR)? Used to determine thickness, density and roughness for single and multilayer stacks on semiconductor wafers, XRR analysis can be performed on both crystalline and amorphous materials.

How it works — an X-ray beam is reflected off of a sample at very small diffraction angles generating a reflectivity pattern. A simulation of the reflectivity pattern gives an accurate measurement of thickness, interface roughness, and layer density for either crystalline or amorphous thin films.
