Domain-wall engineering and topological defects in ferroelectric and ferroelastic materials
Nataf, Guillaume; Gregg, J Marty; Meier, Dennis Gerhard; Hlinka, Jiri; Salje, Ekhard K. H. (Journal article, 2020)Ferroelectric and ferroelastic domain walls are 2D topological defects with thicknesses approaching the unit cell level. When this spatial confinement is combined with observations of emergent functional properties, such ... -
Observation of Unconventional Dynamics of Domain Walls in Uniaxial Ferroelectric Lead Germanate
Bak, Ohheum; Holstad, Theodor Secanell; Lu, Haidong; Evans, Donald; Hunnestad, Kasper Aas; Wang, Bo; Becker, Petra; Bohatý, Ladislav; Helvoort, Antonius T. J. van; Gregg, J Marty; Meier, Dennis Gerhard; Gruverman, Alexei (Peer reviewed; Journal article, 2020)Application of scanning probe microscopy techniques such as piezoresponse force microscopy (PFM) opens the possibility to re‐visit the ferroelectrics previously studied by the macroscopic electrical testing methods and ...
