Observation of Antiferroelectric Domain Walls in a Uniaxial Hyperferroelectric
Michele Conroy, Didrik René Småbråten, Colin Ophus +11
Ferroelectric domain walls are a rich source of emergent electronic properties and unusual polar order. Recent studies showed that the configuration of ferroelectric walls can go w…
Controlling local resistance via electric-field induced dislocations
D. M. Evans, D. R. Småbråten, T. S. Holstad +7
Dislocations are one-dimensional (1D) topological line defects where the lattice deviates from the perfect crystal structure. The presence of dislocations transcends condensed matt…
Oxygen vacancies in bulk and at neutral domain walls in hexagonal YMnO
Sandra H. Skjærvø, Didrik R. Småbråten, Nicola A. Spaldin +2
We use density functional calculations to investigate the accommodation and migration of oxygen vacancies in bulk hexagonal YMnO, and to study interactions between neutral ferr…
Electronic bulk and domain wall properties in B-site doped hexagonal ErMnO
T. S. Holstad, D. M. Evans, A. Ruff +8
Acceptor and donor doping is a standard for tailoring semiconductors. More recently, doping was adapted to optimize the behavior at ferroelectric domain walls. In contrast to more…
