Experimental Techniques in Materials Characterization, Lecture # 17
Introduction to X-Ray Diffraction (XRD)
"Experimental Techniques in Materials Characterization" is a special course designed for the M.Phil. and PhD researchers working in the field of Materials Science, Nanotechnology, Physics, Chemistry and Materials Engineering, etc. In this course, the researchers will learn about the popular materials characterization techniques like:
#X-Ray Diffraction (XRD)
#History of X-Ray Diffraction
#How Diffraction Works
0:00 Experimental Techniques in Materials Characterization Lecture # 17
0:34 Introduction
2:23 History of X-Ray Diffraction
4:31 How Diffraction Works
7:05 Crystalline materials are characterized by the orderly periodic arrangements of atoms.
9:25 The atoms in a crystal are a periodic array of coherent scatterers and thus can diffract light.
11:01 X-Ray Powder Diffraction (XRPD) uses information about the position, intensity, width, and shape of diffraction peaks in a pattern from a polycrystalline sample.
13:01 Bragg's law is a simplistic model to understand what conditions are required for diffraction.
17:18 Our powder diffractometers typically use the Bragg-Brentano geometry.
