AFM Tools for Piezoelectrics and Ferroelectrics Research

Piezoresponse force microscopy (PFM) is an atomic force microscopy technique that can be used to characterize the electromechanical coupling underlying the functionality of many material systems, including piezoelectrics, ferroelectrics, and certain biological materials. An electrical stimulus is applied locally to the sample through the AFM tip while the mechanical response, on the order of ~1-100 pm/V, is simultaneously measured.  This technique is relevant to both basic materials science research and a rich field of applied technologies. Asylum Research is recognized as the world leader in commercial PFM technology by providing crosstalk-free, high sensitivity PFM measurements using a variety of advanced and proprietary measurement techniques and capabilities.

  • Image the sample's electromechanical response at a fixed frequency or by tracking resonance (with DART or Band Excitation).
  • High tip bias voltages possible for enhanced sensitivity - up to  ±150 V on Cypher™ and MFP‑3D Infinity™ and up to ±220 V on MFP‑3D Origin™ and Origin+.
  • Switching spectroscopy to generate piezoresponse amplitude "butterfly" loops and phase "hysteresis" loops.  
  • Built-in lithography tools to write domains and complex patterns. Tip bias can be varied continuously using the grayscale of an imported bitmap.  
  • Vector PFM to reconstruct real space polarization orientation.
  • Compatible with various environmental stages and accessories to allow for heating and cooling, or to subject the sample to humidity, gas perfusion, or applied magnetic fields.
