Marty Gregg leads the nanoscale ferroelectric activity in QUB. His main themes of research to date have been:

  • The study of ferroelectric thin films and superlattices grown by Pulsed Laser Deposition (PLD);
  • The characterisation and understanding of well-controlled nanoscale ferroelectric entities cut from high purity bulk crystals using Focused Ion Beam milling;
  • Control of domain wall dynamics and functional properties.

Microscopy is critical and consequently Marty has been heavily involved in electron, ion and scanning probe techniques for most of his career.
