Intrinsic and extrinsic conduction contributions at nominally neutral domain walls in hexagonal manganites
J. Schultheiß, J. Schaab, D. R. Småbråten +5
Conductive and electrostatic atomic force microscopy (cAFM and EFM) are used to investigate the electric conduction at nominally neutral domain walls in hexagonal manganites. The E…
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…
Charged domain walls in improper ferroelectric hexagonal manganites and gallates
Didrik R. Småbråten, Quintin N. Meier, Sandra H. Skjærvø +3
Ferroelectric domain walls are attracting broad attention as atomic-scale switches, diodes and mobile wires for next-generation nanoelectronics. Charged domain walls in improper fe…
Electrical half-wave rectification at ferroelectric domain walls
J. Schaab, S. H. Skjærvø, S. Krohns +10
Ferroelectric domain walls represent multifunctional 2D-elements with great potential for novel device paradigms at the nanoscale. Improper ferroelectrics display particularly prom…
Goldstone-like phonon modes in a (111)-strained perovskite
A. Marthinsen, S. M. Griffin, M. Moreau +3
Goldstone modes are massless particles resulting from spontaneous symmetry breaking. Although such modes are found in elementary particle physics as well as in condensed matter sys…
