Gate-controlled supercurrent effect in dry-etched Dayem bridges of non-centrosymmetric niobium rhenium
Jennifer Koch, Carla Cirillo, Sebastiano Battisti +10
The application of a gate voltage to control the superconducting current flowing through a nanoscale superconducting constriction, named as gate-controlled supercurrent (GCS), has…
Demonstration of high-impedance superconducting NbRe Dayem bridges
S. Battisti, J. Koch, A. Paghi +10
Here we demonstrate superconducting Dayem-bridge weak-links made of different stoichiometric compositions of NbRe. Our devices possess a relatively high critical temperature, norma…
Dirac surface states, multiorbital dimerization and superconductivity in Nb- and Ta-based A15 compounds
Raghottam M. Sattigeri, Giuseppe Cuono, Ghulam Hussain +5
Using first-principle calculations, we investigate the electronic, topological and superconducting properties of NbX (X = Ge, Sn, Sb) and TaY (Y = As, Sb, Bi) A15 compounds…
Single-crystalline YIG flakes with uniaxial in-plane anisotropy and diverse crystallographic orientations
Roman Hartmann, Seema, Ivan Soldatov +12
We study Y3Fe5O12 (YIG) flakes that we produce via mechanical cleaving and exfoliation of YIG single crystals. By characterizing their structural and magnetic properties, we find t…
Signature of long-ranged spin triplets across a two-dimensional superconductor/helimagnet van der Waals interface
Alfredo Spuri, Danilo Nikolić, Subrata Chakraborty +7
The combination of a superconductor with a magnetically inhomogeneous material has been established as an efficient mechanism for the generation of long-ranged spin-polarized (spin…
Effects of fabrication routes and material parameters on the control of superconducting currents by gate voltage
Leon Ruf, Tosson Elalaily, Claudio Puglia +12
The control of a superconducting current via the application of a gate voltage has been recently demonstrated in a variety of superconducting devices. Although the mechanism underl…
Materials challenges for SrRuO3: from conventional to quantum electronics
Mario Cuoco, Angelo Di Bernardo
The need for faster and more miniaturised electronics is challenging scientists to develop novel forms of electronics based on quantum degrees of freedom different from electron ch…
Microscopic theory of supercurrent suppression by gate-controlled surface depairing
Subrata Chakraborty, Danilo Nikolić, Juan Carlos Cuevas +5
Recently gate-mediated supercurrent suppression in superconducting nano-bridges has been reported in many experiments. This could be either a direct or an indirect gate effect. The…
Gate control of superconducting current: Mechanisms, parameters and technological potential
Leon Ruf, Claudio Puglia, Tosson Elalaily +14
In conventional metal-oxide semiconductor (CMOS) electronics, the logic state of a device is set by a gate voltage (VG). The superconducting equivalent of such effect had remained…
