Basics of X-Ray Powder Diffraction

High Resolution X-Ray Diffraction (HRXRD) Training • HRXRD is used to analyze epitaxial thin films – Can determine composition, strain/relaxation, lattice parameters (in-plane and out-of-plane), thickness, and defect concentration • X-Ray Reflectivity (XRR) is used to analyze thin films, including amorphous and non-textured films

X-ray thin-film measurement techniques

the X-ray reflectivity curve of a thin film deposited on a Si substrate. Therefore, the X-ray reflectivity technique is a method for determining the layer structure of a thin film. The principles of X-ray reflectivity method will be described in section 5 in greater detail. 3. Useful methods and practices in X-ray reflectivity measurement

the incident X-ray beam; n is an integer. This observation is an example of X-ray wave interference (Roentgenstrahlinterferenzen), commonly known as X-ray diffraction (XRD), and was direct evidence for the periodic atomic structure of crystals postulated for several centuries. n l =2dsinq Bragg’s Law
