Bulk-Free Topological Insulator Bi2Se3 nanoribbons with Magnetotransport Signatures of Dirac Surface States
Gunta Kunakova, Luca Galletti, Sophie Charpentier +6
Many applications for topological insulators (TIs) as well as new phenomena require devices with reduced dimensions. While much progress has been made to realize thin films of TIs…
Induced unconventional superconductivity on the surface states of BiTe topological insulator
Sophie Charpentier, Luca Galletti, Gunta Kunakova +11
Topological superconductivity is central to a variety of novel phenomena involving the interplay between topologically ordered phases and broken-symmetry states. The key ingredient…
Origin and evolution of surface spin current in topological insulators
André Dankert, Priyamvada Bhaskar, Dmitrii Khokhriakov +6
The Dirac surface states of topological insulators offer a unique possibility for creating spin polarized charge currents due to the spin-momentum locking. Here we demonstrate that…
Incipient Berezinskii-Kosterlitz-Thouless transition in two-dimensional coplanar Josephson junctions
D. Massarotti, B. Jouault, V. Rouco +8
Superconducting hybrid junctions are revealing a variety of novel effects. Some of them are due to the special layout of these devices, which often use a coplanar configuration wit…
Josephson coupling in junctions made of monolayer graphene on SiC
B. Jouault, S. Charpentier, D. Massarotti +10
Graphene on silicon carbide (SiC) has proved to be highly successful in Hall conductance quantization for its homogeneity at the centimetre scale. Robust Josephson coupling has bee…
Room Temperature Electrical Detection of Spin Polarized Currents in Topological Insulators
André Dankert, Johannes Geurs, M. Venkata Kamalakar +1
Topological insulators (TIs) are a new class of quantum materials that exhibit spin momentum locking (SML) of massless Dirac fermions in the surface states. Usually optical methods…
Influence of Topological Edge States on the Properties of Al/Bi2Se3/Al Hybrid Josephson Devices
L. Galletti, S. Charpentier, M. Iavarone +9
In superconductor-topological insulator-superconductor hybrid junctions, the barrier edge states are expected to be protected against backscattering, to generate unconventional pro…
Ultra low noise YBCO nanoSQUIDs implementing nanowires
Riccardo Arpaia, Marco Arzeo, Shahid Nawaz +3
We present results on ultra low noise YBaCuO nano Superconducting QUantum Interference Devices (nanoSQUIDs). To realize such devices, we implemented high quality YB…
