Electrostatic topology of ferroelectric domains in YMnO
Tobias Jungk, Ákos Hoffmann, Manfred Fiebig +1
Trimerization-polarization domains in ferroelectric hexagonal YMnO were resolved in all three spatial dimensions by piezoresponse force microscopy. Their topology is dominated…
Lateral Signals in Piezoresponse Force Microscopy at Domain Boundaries of Ferroelectric Crystals
Florian Johann, Tobias Jungk, Martin Lilienblum +2
In piezoresponse force microscopy a lateral signal at the domain boundaries is occasionally observed. In recent years, a couple of experiments have been reported and varying explan…
Sol-Gel Derived Ferroelectric Nanoparticles Investigated by Piezoresponse Force Microscopy
F. Johann, T. Jungk, S. Lisinski +3
Piezoresponse force microscopy (PFM) was used to investigate the ferroelectric properties of sol-gel derived LiNbO nanoparticles. To determine the degree of ferroelectricity we…
Depth Resolution of Piezoresponse Force Microscopy
Florian Johann, Yongjun J. Ying, Tobias Jungk +5
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…
Contrast Mechanisms for the Detection of Ferroelectric Domains with Scanning Force Microscopy
T. Jungk, A. Hoffmann, E. Soergel
We present a full analysis of the contrast mechanisms for the detection of ferroelectric domains on all faces of bulk single crystals using scanning force microscopy exemplified on…
Impact of the tip radius on the lateral resolution in piezoresponse force microscopy
T. Jungk, A. Hoffmann, E. Soergel
We present a quantitative investigation of the impact of tip radius as well as sample type and thickness on the lateral resolution in piezoresponse force microscopy (PFM) investiga…
