Solid State Chemistry: Fundamentals of Crystal Structure

Solid state chemistry is the essential foundation for understanding modern materials science, from semiconductors to advanced battery technology. This course demystifies the structure and properties of the materials that power our world. By the end of this course, you will have a strong grasp of the geometry of crystals, the types of defects that influence material behavior, and the relationship between atomic arrangement and macroscopic properties. What you'll learn: * Understand the seven crystal systems, Bravais lattices, and how to define unit cells in three-dimensional space. * Master calculating packing efficiency for common crystal structures like BCC, FCC, and hexagonal close-packed (HCP) arrangements. * Apply Miller indices to describe crystallographic planes and directions within a lattice. * Analyze point and line defects (Schottky, Frenkel) and understand their role in controlling semiconductor and insulator properties. * Learn the theory behind the electrical, magnetic, and dielectric behavior of solids, including basic band theory concepts. We begin with the foundational concepts of symmetry and crystal systems, progress through detailed lattice geometry and packing calculations, and conclude by examining the physics governing material properties. This course is designed for absolute beginners in physical chemistry or materials science. No prior knowledge of crystallography or advanced physics is required.
