The Braggs were awarded the Nobel Prize in physics in 1915 for their work in determiningcrystal structures beginning with NaCl, ZnS and diamond.

Bragg's law was used to explain the interference pattern of X-rays scattered by crystals, diffraction has been developed to study the structure of all states of matter with any beam, e.g., ions, electrons, neutrons, and protons.

Introduction

Why XRD?• Measure the average spacings between layers or rows of atoms• Determine the orientation of a single crystal or grain• Find the crystal structure of an unknown material• Measure the size, shape and internal stress of small crystalline regions
