ObjectivesAt the end of this module you should be able to:
- Identify classes of solids and describe the bonding mechanisms that hold the solids together;
- Apply the rules of basic crystallography to describe and determine the structures of materials;
- Calculate structure factors for X-ray and neutron Bragg diffraction from crystalline solids;
- Utilise extended and reduced Brillouin Zone schemes to describe wave phenomena in reciprocal space;
- Calculate phonon dispersion relations for simple monatomic and diatomic solids;
- Describe experimental methods of probing the structures and dynamics of solids;
- Discuss and evaluate the effects of the periodic lattice on electrons within a solid.
