#### Learning Outcomes

Subject-specific Knowledge:

- Having studied this module students will have an understanding of the thermodynamics of matter, the four laws of thermodynamics and their application.
- They will have appreciation of distributions of classical and quantum particles leading to a discussion of entropy and temperature.
- They will have the ability to describe the arrangement of atoms in a crystal structure and the diffraction pattern that results in both direct and reciprocal space.
- They will have an understanding of elastic vibrations of atoms in crystals and how these vibrations are quantised into phonons.
- They will have knowledge of the concept of phonons and how these explain the thermal properties of solids.
- They will have knowledge of the breakdown in classical physics and how to apply quantum mechanics to the study of electrons in crystalline solids, the nature of electron states and how metallic, semiconducting and insulating materials arise.
- They will have an appreciation of X-ray and neutron scattering as a probe of crystal structure, vibrational, and electronic properties of solids in 2 and 3 dimensions.
- They will be able to use analytical methods to describe a range of wave phenomena, including interference, diffraction and polarisation, and will be familiar with their applications in optics.

Subject-specific Skills:

- In addition to the acquisition of subject knowledge, students will be able to apply the principles of physics to the solution of predictable and unpredictable problems.
- They will know how to produce a well-structured solution, with clearly-explained reasoning and appropriate presentation.

Key Skills:

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Teaching will be by lectures and tutorial-style workshops.
- The lectures provide the means to give concise, focused presentation of the subject matter of the module. The lecture material will be defined by, and explicitly linked to, the contents of the recommended textbooks for the module, thus making clear where students can begin private study. When appropriate, the lectures will also be supported by the distribution of written material, or by information and relevant links on DUO.
- Regular problem exercises and workshops will give students the chance to develop their theoretical understanding and problem solving skills.
- Students will be able to obtain further help in their studies by approaching their lecturers, either after lectures or at other mutually convenient times.
- Student performance will be summatively assessed through an examination and formatively assessed through problem exercises and progress tests. The examination will provide the means for students to demonstrate the acquisition of subject knowledge and the development of their problem-solving skills. The problem exercises, progress tests and workshops will provide opportunities for feedback, for students to gauge their progress and for staff to monitor progress throughout the duration of the module.
