We demonstrate superconducting vertical interconnect access (VIA) contacts to a monolayer of molybdenum disulfide (MoS$_2$), layered semiconductor with highly relevant electronic and optical properties. As contact material we use MoRe, superconductor high critical magnetic field temperature. The electron transport is mostly dominated by single superconductor/normal conductor junction clear gap....

The electronic properties relevant to superconductivity are reported for bulk Ta-Hf and Ta-Zr body centered cubic alloys, in a large part determine whether their suitable potential use superconducting qbits. unit cell sizes increase with increasing alloying. results of magnetic susceptibility, electrical resistivity, heat capacity characterization reported. While elemental Ta is type I supercon...

In the intermediate state of a thin type-I superconductor magnetic flux penetrates in a disordered set of highly branched and fingered macroscopic domains. To understand these shapes, we study in detail a recently proposed ‘‘current-loop’’ model @R. E. Goldstein, D. P. Jackson, and A. T. Dorsey, Phys. Rev. Lett. 76, 3818 ~1996!# that models the intermediate state as a collection of tense curren...

We study properties of Abrikosov-Nielsen-Olesen (ANO) strings with the Coleman-Weinberg (CW) potential, which we call CW-ANO strings. While scale-invariant scalar potential has a topologically trivial vacuum admitting no at classical level, quantum correction allows nontrivial vacua and stable string solutions. find that system CW exhibits significant difference from conventional Abelian-Higgs ...

We study mechanisms of absorption in two essentially different types superconductor-insulator-normal metal-insulator-superconductor (SINIS) bolometers with absorber directly placed on Si wafer and suspended above the substrate. The figure merit for quantum photon is efficiency equal to number detected electrons one photon. dramatically dependent phonon losses substrate electrodes, electron ener...

We discuss the main characteristics that must be satisfied by Josephson junctions for metrological applications and, specifically, in the development of voltage standards of new generation. Data reported in the literature for the most established technologies, like SNS (Superconductor-Normal conductor-Superconductor), SINIS (SuperconductorInsulator-Normal conductor-Insulator-Superconductor) and...

The Dirac semimetal ${\mathrm{PdTe}}_{2}$ becomes superconducting at a temperature ${T}_{c}=1.6$ K. Thermodynamic and muon spin rotation experiments support type-I superconductivity, which is unusual for binary compound. A key property of superconductor the intermediate state, presents coexistence normal domains magnetic fields lower than thermodynamic critical field ${H}_{c}$. We present scann...

We incorporate the Seiberg-Witten map of noncommutative theory in classical London type-I superconductivity when an external magnetic field is applied. After defining Maxwell potentials, we derive equation for supercurrent as a function parameter, up to second order gauge fields expansion. Keeping track effects fields, argue that can be cast permeability superconductor emergent property materia...
