PHYS3393 Quantum Matter**This module is not approved as a discovery module**

### Objectives

At the end of this module you should be able to:- discuss and evaluate the effects of the periodic lattice on electrons within a solid

- describe the physics of phonons (quantised lattice vibrations) and their effect in common material physics such as heat capacity and conductivity

- calculate scattering rates for electrons in metallic conductors due to phonons, impurities an electron interactions (Fermi liquid);

- understand the concept and physics of electronic quasiparticles.

- describe the principles of operation and calculate current voltage characteristics for simple semiconductor devices and lasers;

- use the physical principles for semiconductors to perform basic conceptual designs of electronic devices

- account for differences to the bulk, and perform calculations of, electron transport in nanoscale conductors and systems of reduced dimensionality.

- apply the knowledge in low dimensional physics to current research in the Quantum Hall effect, plasmon resonance and Coulomb blockade.

- understand the principles of ferroelectric materials.

- describe the phenomenology and classical understanding of superconductivity.

**Learning outcomes**

Students will be able to demonstrate knowledge, understanding and application of:

1. The physics of phonons and their contribution to the thermal properties of materials.

2. Electron interactions (e.g. Fermi liquid) and scattering mechanisms.

3. The origin of effects observed in, and applications of, semiconductors in device physics.

4. Nanoscale effects such as optical and electron transport properties of low dimensional systems.

5. Present scientific concepts, and results either orally or in extended formal scientific English with illustrations and figures and references to literature sources as necessary.

**Skills outcomes**

Ability to solve crystal structures and relate structural properties and functionality.
