is a rapid rise in the extent of R&D activities leading to the integration of ferroelectric thin films in commercial devices. This tutorial covers the following topics:

  • Introduction to material types, ferroelectric films, and a brief history of the field.
  • Applications of ferroelectric films, including recent commercial developments and materials science issues. The section will be divided into the following categories:
    • Ferroelectric nonvolatile memories
    • Ferroelectric films for DRAMs and other capacitor applications
    • Ferroelectric films for optical applications
    • Piezoelectric and pyroelectric applications
    • Miscellaneous applications
