Hybrid antiferroelectric-ferroelectric domain walls in noncollinear antipolar oxides
Ivan N. Ushakov, Mats Topstad, Muhammad Z. Khalid +15
Antiferroelectrics are emerging as advanced functional materials and are fertile ground for unusual electric effects. For example, they enhance the recoverable energy density in en…
Local doping of an oxide semiconductor by voltage-driven splitting of anti-Frenkel defects
Jiali He, Ursula Ludacka, Kasper A. Hunnestad +12
Layered oxides exhibit high ionic mobility and chemical flexibility, attracting interest as cathode materials for lithium-ion batteries and the pairing of hydrogen production and c…
Tailoring MBE Growth of c-Mn3Sn Directly on MgO (111): From Islands to Film
Longfei He, Ursula Ludacka, Payel Chatterjee +3
We present our study of (0001) oriented MnSn (c-MnSn) thin films synthesized directly on an MgO (111) substrate via molecular beam epitaxy. We identify a growth window wher…
Ferroelectric domain walls for environmental sensors
L. Richarz, I. C. Skogvoll, E. Y. Tokle +9
Domain walls in ferroelectric oxides provide fertile ground for the development of next-generation nanotechnology. Examples include domain-wall-based memory, memristors, and diodes…
