Condensed Matter Physics I module (PH41007)

Condensed matter physics is the science behind the solid and liquid materials all around us. These range from semiconductors in your phone to the magnetic metals in your headphones.

In this module, you’ll explore how the structure and behaviour of atoms in solids determine everyday properties. These include strength, conductivity, and magnetism.

You’ll begin by looking at how atoms are arranged in crystals. You will study how waves interact with this structure and how diffraction can be used to "see" inside solids.

You’ll then examine vibrations in the atomic lattice, called phonons, which affect heat flow. You will also explore how electrons move through materials. This includes why metals conduct and how semiconductors power modern electronics.

Finally, you will study band structures, the Fermi surface, and the magnetic properties of materials.

This module provides the foundations for understanding how modern materials and devices work. It also prepares you for further study and research in solid-state physics, quantum materials, and applied engineering.

What you will learn

In this module, you will:

• learn about crystal structures and how we measure them using diffraction
• explore atomic vibrations (phonons) and their role in thermal conductivity
• understand how electrons behave in solids and how this leads to conduction
• study band theory, semiconductors, and simple models of electron behaviour
• investigate magnetic properties and the structure of the Fermi surface

By the end of this module, you will be able to:

• identify different crystal structures and explain how diffraction reveals atomic arrangements
• describe how phonons influence thermal properties of materials
• apply models of electron behaviour to understand conductivity and band structure
• explain the basic principles behind semiconductors and their applications
