Imaging and structure analysis of ferroelectric domains, domain walls, and vortices by scanning electron diffraction
Ursula Ludacka, Jiali He, Shuyu Qin +9
Direct electron detectors in scanning transmission electron microscopy give unprecedented possibilities for structure analysis at the nanoscale. In electronic and quantum materials…
Optimizing compositional and atomic-level information of oxides in atom probe tomography
Kasper Hunnestad, Constantinos Hatzoglou, Francois Vurpillot +5
Atom probe tomography (APT) is a 3D analysis technique that offers unique chemical accuracy and sensitivity with sub-nanometer spatial resolution. Recently, there is an increasing…
Moiré Fringes in Conductive Atomic Force Microscopy
L. Richarz, J. He, U. Ludacka +4
Moiré physics plays an important role for the characterization of functional materials and the engineering of physical properties in general, ranging from strain-driven transport p…
The third dimension of ferroelectric domain walls
Erik D. Roede, Konstantin Shapovalov, Thomas J. Moran +7
Ferroelectric domain walls are quasi-2D systems that show great promise for the development of non-volatile memory, memristor technology and electronic components with ultra-small…
Atomic-scale 3D imaging of individual dopant atoms in a complex oxide
K. A. Hunnestad, C. Hatzoglou, Z. M. Khalid +6
A small percentage of dopant atoms can completely change the physical properties of the host material. For example, chemical doping controls the electronic transport behavior of se…
Charged ferroelectric domain walls for deterministic a.c. signal control
J. Schultheiß, E. Lysne, L. Puntigam +5
The direct current (d.c.) conductivity and emergent functionalities at ferroelectric domain walls are closely linked to the local polarization charges. Depending on the charge stat…
