Negative charging energy in LaAlO/SrTiO quantum dots induced by SrTiO polarization
J. Czarnecki, A. Sierant, B. Szafran +12
We propose a microscopic mechanism for the negative charging energy in LaAlO/SrTiO quantum dots, arising from the electrostatic image charge associated with the paraelectri…
Magnetic contacts on freestanding superconducting LaAlO/SrTiO micromembranes
Thies Jansen, Pinelopi Konstantinopoulou, Niklas Martin +5
The superconducting two-dimensional electron gas (2DEG) at the LaAlO/SrTiO (LAO-STO) interface is a promising platform for superconducting spintronics, however, integrating…
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…
Phase transitions of LaMnO and SrRuO from DFT + U based machine learning force fields simulations
Thies Jansen, Geert Brocks, Menno Bokdam
Perovskite oxides are known to exhibit many magnetic, electronic and structural phases as function of doping and temperature. These materials are theoretically frequently investiga…
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…
Strain-Induced Room-Temperature Ferroelectricity in SrTiO Membranes
Ruijuan Xu, Jiawei Huang, Edward S. Barnard +11
Advances in complex oxide heteroepitaxy have highlighted the enormous potential of utilizing strain engineering via lattice mismatch to control ferroelectricity in thin-film hetero…
