Dynamic behaviour in piezoresponse force microscopy [PDF]

Nanotechnology, 2006
Frequency dependent dynamic behavior in Piezoresponse Force Microscopy (PFM) implemented on a beam-deflection atomic force microscope (AFM) is analyzed using a combination of modeling and experimental measurements. The PFM signal comprises contributions from local electrostatic forces acting on the tip, distributed forces acting on the cantilever, and ...

Synthesis and Nanoscale Characterization of LiNbO3 Thin Films Deposited on Al2O3 Substrate by RF Magnetron Sputtering under Electric Field [PDF]

Журнал нано- та електронної фізики, 2016
LiNbO3 thin films were deposited on Al2O3 substrates by RF-magnetron sputtering with in-situ electric field to study the self-polarization effect. The films have been characterized crystallographically by x-ray diffraction, and morphologically by atomic ...

Materials contrast in piezoresponse force microscopy [PDF]

Applied Physics Letters, 2006
Piezoresponse force microscopy (PFM) contrast in transversally isotropic material corresponding to the case of c+-c− domains in tetragonal ferroelectrics is analyzed using Green’s function theory by Felten et al. [J. Appl. Phys. 96, 563 (2004)]. A simplified expression for PFM signal as a linear combination of relevant piezoelectric constant is ...

A Piezoresponse Force Microscopy Study of Ca_xBa_1-xNb₂O₆ Single Crystals. [PDF]

Materials (Basel), 2017
Polar structures of CaxBa1-xNb2O6 (CBN100x) single crystals were investigated using piezoresponse force microscopy. Increasing Ca content results in decreasing domain size and enhancement of the polar disorder.

Ultrasound-Responsive Piezoelectric Fibrous Membrane Promotes Neurological Recovery After TBI by Modulating Microglial Polarization via Restoring Mitochondrial Dynamic Homeostasis. [PDF]

Adv Sci (Weinh)
We demonstrate a novel therapy for traumatic brain injury TBI using a LIPUS‐responsive Piezoelectric fibrous membrane. It targets microglial mitochondria via in situ electrical signals, restoring homeostasis and reducing oxidative stress to promote an anti‐inflammatory M2 phenotype.
