Objectives of the Course To teach what a crystal is, what determines the structure of a crystal, and how such structures are measured experimentally.
To introduce the elementary models for bonding of atoms and molecules in order to understand what binds crystals of different classes: metals, insulators, molecular solids, etc.
To demonstrate the problem of elastic scattering by a crystal using the concept of reciprocal lattice and how calculations separate factors which depend on the lattice and on the basis.
To teach concepts such as phonons (crystal vibrations). Specifically, to demonstrate the features of the vibrations of monatomic and diatomic linear chains and to explain the significance of dispersion curves in three dimensions.
Course Content * Old solid state theories: Einstein, Debye, Drude and Sommerfeld.
* Microscopic structure of matter: atoms, bondings, phases.
* Simple one-dimensional models: lattice vibrations, tight-binding.
* Crystal structure in three dimensions: lattices, reciprocal lattices, Brillouin zones, Miller indices.
* Scattering: Landau and Bragg conditions. Experimental determination of crystal structure.
