High-Voltage Piezoresponse Force Microscopy (PFM)

PFM image of PVDF polymer. The piezoelectric response of PVDF is widely exploited in tactile sensors. PFM lateral amplitude is shown on 3D topography, 2 ?m scan. Sample courtesy D. Guo, Institute of Acoustics, Chinese Academy of Science.

The HV-PFM option on Cypher AFMs enables high sensitivity, high bias, and crosstalk-free measurements on piezoelectrics, including ferroelectrics and multiferroics. The kit includes an integrated high voltage amplifier (±150 V), high voltage cantilever holder, high voltage sample mount, and conductive cantilevers.

Crosstalk-free measurements
High sensitivity and speed
Uses exclusive Dual AC Resonance Tracking (DART)
Enables tip biases up to ±150 V
