XRD is a tool for the investigation of the crystal structures of materials. It is an extremely important analytical tool for researchers in materials related disciplines. This class is intended to provide the students with the knowledge of X-Ray Diffraction (XRD) and its applications. We will mainly cover the following topics in this course: properties of x-rays, crystallography, geometry of crystals, diffraction and experimental methods like powder XRD and applications like crystal size, crystal structure, amorphous materials, precise parameter measurements, phase diagram determination and multiphase quantitative analysis. There will be two midterm exams and a final exam in addition to several homework problems. But your performance in the labs will also be monitored.
