Aims
After completing this TLP, you should:
- Be aware of the atomic requirements for ferroelectricity.
- Understand how this atomic structure leads to spontaneous polarisation, and how this polarisation can be switched.
- Understand how this polarisation leads to the interesting electrical properties displayed by ferroelectrics.
- Understand how these properties are made use of in today's technologies.
