Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…

Phase controlled multi-terminal Josephson junction in ternary hybrid nanowire
Sabbir A. Kahn, Lukas Stampfer, Sara Marti-Sanchez +7
This work presents multiterminal Josephson junctions in hybrid semiconductor-superconductor InAsSb-Al nanocrosses. Hybrid nanocrosses are grown using molecular beam epitaxy and are…

Imaging the suppression of ferromagnetism in LaMnO by metallic overlayers
Bart Folkers, Thies Jansen, Thijs J. Roskamp +7
LaMnO (LMO) thin films epitaxially grown on SrTiO (STO) usually exhibit ferromagnetism above a critical layer thickness. We report the use of scanning SQUID microscopy (SSM…
