Learning Outcomes

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

Explain and apply the concept of reciprocal space in the context of diffraction, electronic structure and lattice dynamics.

Distinguish material classes such as crystals, polymers, liquids, and glasses according to their structure and describe common crystal structures.

Demonstrate an understanding of electronic structure and the basic mechanisms of electrical conductivity.

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

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

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