Piezoresponse and Electrochemical Force Microscopy and Spectroscopy | Virtual Academy by Asylum Research - Group

Asylum Research recently hosted a virtual academy on Piezoresponse and Electrochemical Force Microscopy and Spectroscopy. The academy was organized by renowned leaders in the field, Sergei V. Kalinin and Roger Proksch, and features lectures from experts around the world. The introductory keynote lecture was given by Prof. Andrei Kholkin of the University of Aveiro, a prominent figure in the field of ferroelectric materials and measurement technologies.

The PFM Academy aimed to provide a comprehensive introduction to the field, covering recent developments and integrating the latest advances with established theory and practice. This especially benefits newcomers to the field of ferroelectrics with learning about advances in material analysis, including binary ferroelectric materials like hafnia and nitrides, twisted bilayers, and layered ferroelectrics. On the instrumental side, the academy explored new interferometric detection systems for quantitative measurements of electromechanical properties, as well as machine learning and automated experiments for analyzing large PFM datasets.

The virtual academy followed the tradition of the PFM schools that began in 2006 at ORNL. The curriculum consists of two hours of virtual lectures, held twice a week over a five-week period, allowing attendees to tailoring your learning to your specific needs.

We believe it is important to ensure this highly valuabe learning resouce remians accessible, and so all these lectures are available to watch on-demand.
