  journal={arXiv: Superconductivity},
Device-based tunnel spectroscopy of superconductors was first performed by Giaever, whose seminal work provided clear evidence for the spectral gap in the density of states (DOS) predicted by the Bardeen-Cooper-Schrieffer (BCS) theory. Since then, tunnel-barrier-based heterostructure devices have revealed myriad physical phenomena and found a range of applications. Most of these devices rely on a limited number of oxides, which form high-quality insulating, non-magnetic barriers. These barriers… Expand


Superconductivity protected by spin-valley locking in ion-gated MoS2
The electric-field-induced superconducting properties of MoS2 are investigated by means of magneto-transport measurements, uncovering evidence of spin–momentum locking. Symmetry-breaking has beenExpand
Signatures of Phonon and Defect-Assisted Tunneling in Planar Metal-Hexagonal Boron Nitride-Graphene Junctions.
Electron tunneling spectroscopy measurements on van der Waals heterostructures consisting of metal and graphene electrodes separated by atomically thin hexagonal boron nitride tunnel barriers are reported, leading to "Coulomb diamonds" in the tunneling conductance. Expand
Transition from metallic to tunneling regimes in superconducting microconstrictions: Excess current, charge imbalance, and supercurrent conversion
We propose a simple theory for the $I\ensuremath{-}V$ curves of normal-superconducting microconstriction contacts which describes the crossover from metallic to tunnel junction behavior. The detailedExpand
Ubiquitous V-shape density of states in a mixed state of clean limit type II superconductors.
It is demonstrated theoretically and experimentally that the low energy density of states N(E) is described by a singular V-shape form N(E)=N(0)(H)+alpha|E|+O(E2) for all clean superconductors in aExpand
Evidence for two-dimensional Ising superconductivity in gated MoS2
This study provides experimental evidence of an Ising superconductor, in which spins of the pairing electrons are strongly pinned by an effective Zeeman field. Expand
Are "pinholes" the cause of excess current in superconducting tunnel junctions? A study of Andreev current in highly resistive junctions.
It is argued that the observations rule out pinholes as the origin of the excess current and the quasiclassical Keldysh-Green function theory is used to quantify single- and two-particle tunneling and finds good agreement with experiment over 2 orders of magnitude in transparency. Expand

The electronic structure of a vortex line in a type-II superconductor is calculated self-consistently in the framework of the Bogoliubov--de Gennes theory, and the resulting local density of states has a characteristic star shape in real space, whose orientation is energy dependent, in agreement with recent STM experiments.

Break-junction tunneling on MgB2
Abstract Tunneling data on magnesium diboride, MgB 2 , are reviewed with a particular focus on superconductor–insulator–superconductor (SIS) junctions formed by a break-junction method. TheExpand
Quasiparticle spectra of 2 H -NbSe 2 : Two-band superconductivity and the role of tunneling selectivity
We have studied the superconducting state of 2H−NbSe2 by scanning tunneling spectroscopy along two different crystal orientations, the c and the a/b axes. Along the c axis a large gap is dominant inExpand
Field dependence of the zero-energy density of states around vortices in an anisotropic-gap superconductor
It is shown theoretically that the Sommerfeld coefficient $\gamma(B)$ in the mixed state contains useful information on the gap topology in a superconductor. We accurately evaluate $\gamma(B)$Expand
