Module summary

This module explores the influence of quantum phenomena on the physics and electronic properties of condensed matter systems, including the physics and operation of semiconductors and superconductors.

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.

- 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 and electronic 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; e.g. diodes, solar cells, light-emitting diodes, lasers and introduction to transistors.

4. Molecular orbital levels and electron hopping transport in organic semiconductors for e.g. photovoltaics.

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

6. Basic Electronic structure and phenomenology of Dirac materials

7. London equations and Cooper pairs; origin of the physics of superconductors.
