Nanoscale wireframe SQUID on a cantilever by corner lithography
Thijs J. Roskamp, Tim Horstink, Melissa J Goodwin +5
We present the fabrication of nanoscale superconducting quantum interference devices (SQUIDs) at the apex of wireframe tips on self-aligned superconducting cantilever probes. The p…
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…
Gate-tuned Anomalous Hall Effect Driven by Rashba Splitting in Intermixed LaAlO3/GdTiO3/SrTiO3
N. Lebedev, M. Stehno, A. Rana +6
The Anomalous Hall Effect (AHE) is an important quantity in determining the properties and understanding the behavior of the two-dimensional electron system forming at the interfac…
Efficient charge modulation in ultrathin LaAlO-SrTiO field-effect transistors
A. E. M. Smink, B. Prabowo, B. Stadhouder +4
At the LaAlO-SrTiO interface, electronic phase transitions can be triggered by modulation of the charge carrier density, making this system an excellent prospect for the re…
Tailoring Vanadium Dioxide Film Orientation using Nanosheets: A Combined Microscopy, Diffraction, Transport and Soft X-ray in Transmission Study
Phu Tran Phong Le, Kevin Hofhuis, Abhi Rana +17
VO2 is a much-discussed material for oxide electronics and neuromorphic computing applications. Here, heteroepitaxy of vanadium dioxide (VO2) was realized on top of oxide nanosheet…
Analysing Magnetism Using Scanning SQUID Microscopy
P. Reith, X. Renshaw Wang, H. Hilgenkamp
Scanning superconducting quantum interference device microscopy (SSM) is a scanning probe technique that images local magnetic flux, which allows for mapping of magnetic fields wit…
Nonlocal Andreev reflection, fractional charge and current-phase relation in topological bilayer exciton condensate junctions
M. Veldhorst, M. Hoek, M. Snelder +3
We study Andreev reflection and Josephson currents in topological bilayer exciton condensates (TEC). These systems can create 100% spin entangled nonlocal currents with high amplit…
Josephson supercurrent in a topological insulator without a bulk shunt
M. Snelder, C. G. Molenaar, Y. Pan +8
A Josephson supercurrent has been induced into the three-dimensional topological insulator Bi1.5Sb0.5Te1.7Se1.3. We show that the transport in Bi1.5Sb0.5Te1.7Se1.3 exfoliated flake…
Modulation of conductance and superconductivity by top-gating in LaAlO3/SrTiO3 2-dimensional electron systems
P. D. Eerkes, W. G. van der Wiel, H. Hilgenkamp
We report the electrical top-gating of a 2-dimensional electron gas (2DEG) formed at the LaAlO3/SrTiO3 interface, using electron-beam evaporated Au gate electrodes. In these struct…
Band offsets and density of Ti3+ states probed by X-ray photoemission on LaAlO3/SrTiO3 heterointerfaces and their LaAlO3 and SrTiO3 bulk precursors
G. Drera, G. Salvinelli, A. Brinkman +6
A set of LaAlO3/SrTiO3 (LAO-STO) interfaces has been probed by X-ray photoemission spectroscopy in order to contrast and compare the effects of LAO overlayer thickness and of the g…
Optimizing the Majorana character of SQUIDs with topologically non-trivial barriers
M. Veldhorst, C. G. Molenaar, C. J. M. Verwijs +2
We have modeled SQUIDs with topologically non-trivial superconducting junctions and performed an optimization study on the Majorana fermion detection. We find that the SQUID parame…
Superconducting Quantum Interference Device based on MgB2 nanobridges
A. Brinkman, D. Veldhuis, D. Mijatovic +4
The recently discovered superconductor MgB2, with a transition temperature of 39K, has significant potential for future electronics. An essential step is the achievement of Josephs…
