Electromechanical coupling is one of the fundamental mechanisms underlying the functionality of many materials. These include inorganic macro-molecular materials, such as piezo- and ferroelectrics, as well as many biological systems. Necessity for probing electromechanical functionalities has led to the development of Piezoresponse Force Microscopy (PFM), an ideal tool for local nanoscale imaging, spectroscopy, and manipulation of piezoelectric and ferroelectric materials.
This first introduction of a two-part series that will cover topics including theory, electromechanical coupling, limitations of conventional methodologies, and advances in instrumentation such as Switching Spectroscopy PFM, Dual AC™ Resonance Tracking (DART) and Band Excitation (for measuring a more complete frequency response.
Presenters include PFM pioneers 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.
