Correlated domain and crystallographic orientation mapping in uniaxial ferroelectric polycrystals by interferometric vector piezoresponse force microscopy
Ruben Dragland, Jan Schultheiß, Ivan N. Ushakov +2
Ongoing advances in scanning probe microscopy techniques are continually expanding the possibilities for nanoscale characterization and correlated studies of functional materials.…
Hybrid antiferroelectric-ferroelectric domain walls in noncollinear antipolar oxides
Ivan N. Ushakov, Mats Topstad, Muhammad Z. Khalid +15
Antiferroelectrics are emerging as advanced functional materials and are fertile ground for unusual electric effects. For example, they enhance the recoverable energy density in en…
Non-destructive tomographic nanoscale imaging of ferroelectric domain walls
Jiali He, Manuel Zahn, Ivan N. Ushakov +8
Extraordinary physical properties arise at polar interfaces in oxide materials, including the emergence of two-dimensional electron gases, sheet-superconductivity, and multiferroic…
Quantitative 3D mapping of chemical defects at charged grain boundaries in a ferroelectric oxide
K. A. Hunnestad, J. Schultheiß, A. C. Mathisen +4
Polar discontinuities and structural changes at oxide interfaces can give rise to a large variety of electronic and ionic phenomena. Related effects have been intensively studied i…
