Learning Outcomes

On successful completion of this module students should be able to:

1. Utilise the concept of reciprocal space in the context of diffraction, electronic structure and lattice dynamics.

2. Discuss the properties of material classes such as crystals, polymers, liquids and glasses according to their structure, and describe common crystal structures.

3. Appraise the role of electronic structure in the basic mechanisms of electrical conductivity.

4. Discuss the interaction of solids with magnetic fields and distinguish dia-, para- and ferromagnetism.

5. Analyse the magnetic properties of solids in terms of collective magnetic phenomena.

6. Assess the thermal properties of crystal lattices using the Einstein and Debye models and predict their dispersion relations and heat capacities.

Brief description

This course provides the physics behind the atomic, electronic and magnetic structure of materials, their lattice dynamics and mechanical and thermal properties. Starting from descriptions of crystal structures, concepts such as reciprocal space, energy bands, collective magnetism and phonons are introduced.
