28: Ferroelectric Materials

  • Page ID

    Learning Objectives

    On completion of 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.

    Before you start

    This TLP should be fairly self-contained, but some knowledge of crystal structures is assumed. It may be helpful to read the teaching and learning package on Crystallography and Atomic Scale Structure Of Materials first.
