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.
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.
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.
“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.”

About Oxford Instruments Asylum Research
Oxford Instruments Asylum Research is the technology leader in atomic force microscopy for both materials and bioscience research. Asylum Research AFMs are used for a wide variety of nanoscience applications in material science, physics, polymers, chemistry, tribology, biomaterials, and bioscience, including emerging applications in energy storage and generation, low-dimensional materials, and biophysics.
Asylum’s MFP-3D family of AFMs includes four different models that span a wide range of performance, applications, and budgets. The new MFP-3D Infinity is the flagship of the family, offering the highest performance, simplest operation, and widest range of capabilities. The MFP-3D Classic, the original MFP-3D offered for mid-range budgets, provides high performance and versatility that exceeds most AFMs. The MFP-3D Origin is the most affordable model, offering the same performance as the MFP-3D Classic with many accessories and an easy upgrade path to advanced capabilities. Finally, the MFP-3D-BIO integrates with an inverted light microscope to support biological and photonic applications.
Cypher is the highest resolution fast scanning AFM and is available in two configurations, the Cypher S and the Cypher ES Environmental AFM. They provide low-drift closed loop imaging for the most accurate images and measurements possible today, >20X faster imaging with small cantilevers, exceptional ease of use, and integrated thermal, acoustic and vibration control – all in a small footprint. Cypher AFMs routinely achieve higher resolution than other AFMs, as demonstrated by single point atomic defects in crystal lattices and imaging of the DNA double helix.
The Cypher ES adds gas and liquid environmental control, temperature control, and enhanced chemical compatibility to the extraordinary performance of the Cypher S.
In addition to the best AFMs, Asylum Research also offers unmatched customer support that is free for the lifetime of the AFM and industry-leading warranties for the lowest cost of ownership of any AFM. Asylum has sales, applications and service staff in offices in the United States, Germany, United Kingdom, Japan, France, China and Taiwan and global distribution.
