R2D2 -- An equivalent-circuit model that quantitatively describes domain wall conductivity in ferroelectric LiNbO
Manuel Zahn, Elke Beyreuther, Iuliia Kiseleva +7
Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two separate mechanisms: (a) the injection/ejection of charge carriers across the Schottky barrier formed at…
Topological polarization networking in uniaxial ferroelectrics
Y. Tikhonov, J. R. Maguire, C. J. McCluskey +8
Discovery of topological polarization textures has put ferroelectrics at the frontier of topological matter science. High-symmetry ferroelectric oxide materials allowing for freedo…
Imaging Ferroelectrics: Charge Gradient Microscopy (CGM) versus Potential Gradient Microscopy (PGM)
Jesi R. Maguire, Hamza Waseem, Raymond G. P. McQuaid +3
In 2014, Charge Gradient Microscopy (CGM) was first reported as a new scanning probe imaging mode, particularly well-suited for the characterisation of ferroelectrics. The implemen…
Influence of charged walls and defects on DC resistivity and dielectric relaxation in Cu-Cl boracite
C. Cochard, T. Granzow, C. M. Fernandez-Posada +5
Charged domain walls form spontaneously in Cu-Cl boracite on cooling through the phase transition. These walls exhibit changed conductivity compared to the bulk and motion consiste…
An empirical approach to measuring interface energies in mixed-phase bismuth ferrite
Stuart R. Burns, Oliver Paull, Ralph Bulanadi +4
In complex oxide heteroepitaxy, strain engineering is a powerful tool to obtain phases in thin films that may be otherwise unstable in bulk. A successful example of this approach i…
Hydrodynamics of Domain Walls in Multiferroics: Impact on Memory Devices
James F. Scott, Donald M. Evans, J. Marty Gregg +1
We show that switching in ferroelectric lead germanate and lead iron tantalate zirconate titanate (PZTFT) does not resemble the equilibrium domain structure evolution of the Landau…
