Further information on descriptions Description: Aims:
The aims of this unit are to introduce students to the basic concepts and models of solid state physics, with an emphasis on crystalline, electronic and magnetic structure.

Learning Outcomes:
After taking this unit the student should be able to:
* know the ways in which crystal structures are described formally and relate structures in real space to those in reciprocal space;
* describe how X-ray and neutron diffraction is related to the properties of the reciprocal lattice, and used in structural studies.
* discuss why classical theories of electrons in solids fail, and why they have to be treated quantum mechanically;
* explain the concept of density of states;
* describe how allowed and forbidden energy bands arise as a result of crystal potentials and how the properties of electrons in allowed energy bands determine the electrical and optical behaviour;
* appreciate the difference between metals, semiconductors and insulators;
* discuss the factors that control the electrical conductivity of metals and semiconductors;
* describe classical theories of diamagnetism, paramagnetism, and the ferromagnetic properties of materials;
* describe how crystalline structures vibrate, and the associated theories of heat capacity.
