Lecture
This lecture covers the principles of crystallography, focusing on cubic systems and the determination of crystal structures through X-ray diffraction. It explains how to index crystallographic planes and directions, the concept of compact stacking, and the use of Miller indices. The lecture also delves into the interaction of x-rays with matter, the diffraction patterns produced, and the interpretation of XRD patterns. Additionally, it explores the arrangement of atoms in crystal structures, the concept of density, and the determination of crystal symmetry. Practical exercises and demonstrations are used to illustrate these concepts.
