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…
Imaging and structure analysis of ferroelectric domains, domain walls, and vortices by scanning electron diffraction
Ursula Ludacka, Jiali He, Shuyu Qin +9
Direct electron detectors in scanning transmission electron microscopy give unprecedented possibilities for structure analysis at the nanoscale. In electronic and quantum materials…
Moiré Fringes in Conductive Atomic Force Microscopy
L. Richarz, J. He, U. Ludacka +4
Moiré physics plays an important role for the characterization of functional materials and the engineering of physical properties in general, ranging from strain-driven transport p…
