Threshold fields for antiparallel ferroelectric domain wall motion
Samrat Choudhury, Yulan Li, Nozomi Odagawa +10
While an ideal antiparallel ferroelectric wall is considered a unit cell in width (~0.5nm), we show using phase field modeling that the threshold field for moving this wall dramati…
Quantitative piezoelectric force microscopy: Influence of tip shape, size, and contact geometry on the nanoscale resolution of an antiparallel ferroelectric domain wall
Lili Tian, Aravind Vasudevarao, Anna N. Morozovska +3
The structure of a single antiparallel ferroelectric domain wall in LiNbO3 is quantitatively mapped by piezoelectric force microscopy (PFM) with calibrated probe geometry. The PFM…
Dual-Frequency Resonance-Tracking Atomic Force Microscopy
B J Rodriguez, C Callahan, S V Kalinin +1
A dual-excitation method for resonant-frequency tracking in scanning probe microscopy based on amplitude detection is developed. This method allows the cantilever to be operated at…
Direct Measurement of Periodic Electric Forces in Liquids
B. J. Rodriguez, S. Jesse, K. Seal +2
The electric forces acting on an atomic force microscope tip in solution have been measured using a microelectrochemical cell formed by two periodically biased electrodes. The forc…
Fabrication, Dynamics, and Electrical Properties of Insulated SPM Probes for Electrical and Electromechanical Imaging in Liquids
B. J. Rodriguez, S. Jesse, K. Seal +3
Insulated cantilever probes with a high aspect ratio conducting apex have been fabricated and their dynamic and electrical properties analyzed. The cantilevers were coated with sil…
Towards local electromechanical probing of cellular and biomolecular systems in a liquid environment
Sergei V. Kalinin, Brian J. Rodriguez, Stephen Jesse +6
Electromechanical coupling is ubiquitous in biological systems with examples ranging from simple piezoelectricity in calcified and connective tissues to voltage-gated ion channels,…
