Oxford Instruments Asylum Research will host a two-part webinar series on Piezoresponse Force Microscopy (PFM), May 4 and May 6, 2015. Presenters include Dr. Sergei V. Kalinin, Director at the Institute for Functional Imaging of Materials and Theme Leader at the Center for Nanophase Materials Sciences, Oak Ridge National Laboratory, and Asylum Research President and co-founder, Dr. Roger Proksch. The first part of the webinar will be perfect for researchers who are either entirely new to PFM or who perhaps just haven’t heard about the full spectrum of existing PFM capabilities. The second part of the series will focus on new advanced capabilities and applications examples available via CNMS user program and Asylum. 
Single Frequency PFM scan of PZT made at 20 Hz with a Pt coated AC240 Electrilever. The piezoresponse amplitude was overlaid (color) on top of the rendered topography. Domains are visible as regions of nearly constant amplitude, 7.5µm scan. Imaged with the Cypher™ AFM. “Introduction to PFM” broadcasts May 4 and will cover the basic theory of PFM and electromechanical coupling, limitations of conventional PFM methodologies, and advances in instrumentation to overcome these limitations including switching spectroscopy PFM, Dual AC™ Resonance Tracking (DART) PFM, and band excitation measurements. The May 6th webinar will follow-up with discussions on “Advanced PFM Techniques”. Kalinin and Proksch will cover the recent progress in techniques such as Band Excitation (measuring a more complete frequency response), multidimensional PFM spectroscopy, and Electrochemical Strain Microscopy. Challenges and progress in obtaining accurate d33 measurements will also be discussed. “PFM has become the technique of choice for researchers that wish to characterize the functionality of piezoelectric, ferroelectric, and multiferroic materials at the nanoscale,” said Sergei Kalinin. “The recent application of PFM techniques to energy storage and conversion materials has been a beautiful synergy for both application areas.” “Roger Proksch added, “This webinar will be an excellent resource for scientists that want to learn more about basic PFM and for those that want to delve into the advanced theory and techniques. We have learned a tremendous amount about the science of PFM through our collaboration with the global leaders in the field and are excited to share some of these results through our webinar.” Registration for “Introduction to PFM”, May 4, 2015 9:00am PDT session – (http://bit.ly/1NMlkkm) 5:00pm PDT session – (http://bit.ly/1Goh4VK) Registration for “Advanced PFM Techniques”, May 6, 2015 s 9:00am PDT session – (http://bit.ly/1NMllVw) 5:00pm PDT session – (http://bit.ly/1Goh2xa) All registrants will receive a free PFM poster.
