Vector Piezoresponse Force Microscopy [PDF]
Microscopy and Microanalysis, 2006 A novel approach for nanoscale imaging and characterization of the orientation dependence of electromechanical properties-vector piezoresponse force microscopy (Vector PFM)-is described. The relationship between local electromechanical response, polarization, piezoelectric constants, and crystallographic orientation is analyzed in detail.

Minimizing electrostatic interactions from piezoresponse force microscopy via capacitive excitation
Theoretical and Applied Mechanics Letters, 2020 Piezoresponse force microscopy (PFM) has emerged as one of the most powerful techniques to probe ferroelectric materials at the nanoscale, yet it has been increasingly recognized that piezoresponse measured by PFM is often influenced by electrostatic ...

High-temperature piezoresponse force microscopy [PDF]
Applied Physics Letters, 2011 We report high temperature piezoresponse force microscopy (PFM) on 100 nm thick PbZr0.2Ti0.8O3 films fabricated on a miniature heater stage. The microfabricated resistive heater allows local temperature control up to 1000 °C with minimal electrostatic interactions.

Depth resolution of piezoresponse force microscopy [PDF]
Applied Physics Letters, 2009 Given that a ferroelectric domain is generally a three dimensional entity, the determination of its area as well as its depth is mandatory for full characterization. Piezoresponse force microscopy (PFM) is known for its ability to map the lateral dimensions of ferroelectric domains with high accuracy.

Piezoresponse force microscopy for polarity imaging of GaN [PDF]
Applied Physics Letters, 2002 The polarity distribution of GaN based lateral polarity heterostructures is investigated by piezoresponse force microscopy (PFM). Simultaneous imaging of surface morphology, as well as the phase and magnitude of the piezoelectric response, is performed by PFM on a GaN film with patterned polarities on a c-Al2O3 substrate.

Contrast Mechanism Maps for Piezoresponse Force Microscopy [PDF]
Journal of Materials Research, 2002 Piezoresponse force microscopy (PFM) is one of the most established techniques for the observation and local modification of ferroelectric domain structures on the submicron level. Both electrostatic and electromechanical interactions contribute at the tip-surface junction in a complex manner, which has resulted in multiple controversies in the ...

Imaging mechanism of piezoresponse force microscopy in capacitor structures [PDF]
Applied Physics Letters, 2008 The image formation mechanism in piezoresponse force microscopy (PFM) of capacitor structures is analyzed. We demonstrate that the spatial resolution is a bilinear function of film and top electrode thicknesses and derive the corresponding analytical expressions.

Depth resolution in piezoresponse force microscopy
Journal of Applied PhysicsPiezoresponse force microscopy (PFM) is one of the most widespread methods for investigating and visualizing ferroelectric domain structures down to the nanometer length scale. PFM makes use of the direct coupling of the piezoelectric response to the crystal lattice, and hence, it is most often applied to spatially map the three-dimensional (3D) near ...
