Hall Potential Mapping of Conducting Ferroelectric Domain Walls
… phenomenon of distinct conductivity at certain ferroelectric domain walls has the potential to revolutionise nanoelectronics. Complete control over their local carrier properties would allow two-dimensional analogues of semiconducting devices to be dynamically written, effectively supplanting …

Phonon scattering by ferroelectric domain walls in potassium dihydrogen phosphate
I have studied phonon scattering by ferroelectric domain walls in KH2P04 (KDP) using thermal conductivity and phonon imaging measurements of samples in both single-domain (poled) and multidomain states. Domains were eliminated by applying a 2- 3kV /em field using evaporated electrodes. Phonon …

Charged ferroelectric domain walls: the next generation in 2D functional materials
… the properties of charge carriers in conducting ferroelectric domain walls in single crystals of YbMnO3, ErMnO3 and lithium niobate. <br/><br/>Through the use of atomic force microscopy (AFM), electron microscopy and electrical measurements I measured Hall mobility in these systems. This revealed …

Multiscale Simulations of Dynamics of Ferroelectric Domains
Ferroelectric materials exhibiting switchable polarization have been used as critical components in electronics, memory, actuators and acoustics, and electro-optics. The applications of ferroelectric materials heavily rely on the interactions between the polarization and external perturbations, …

An investigation into six-fold domain wall vertices in improper ferroelectrics, and their potential as one dimensional pn-junctions
… the carrier characteristics of conducting ferroelectric domain walls in the improper ferroelectric system ErMnO3. Preliminary measurements reveal that p-type carriers aggregate at tail-to-tail domain walls. QuickField modelling allowed for estimates of the effective cross-sectional area of …
