Proximity-induced superconductivity in three dimensional (3D) topological insulators forms a new quantum phase of matter and accommodates exotic quasiparticles such as Majorana bound states. One of the biggest drawbacks of the commonly studied 3D topological insulators is the presence of conducting bulk that obscures both surface states and low energy bound states. Introducing superconductivity in topological Kondo insulators such as SmB$_6$, however, is promising due to their true insulating…

Kondo effect and superconductivity in niobium with iron impurities
TLDR
It is found that by co-annealing Nb films with Fe in Argon gas at above 400 $$^{\circ }$$ ∘ C for an hour, one can induce a Kondo effect in Nb, and the temperature dependence of the resistance suggests existence of remnant superconductivity at low temperatures even though the system never becomes superconducting.

Symmetry protected Josephson supercurrents in three-dimensional topological insulators.
TLDR
It is shown that the supercurrent is largely carried by surface states, due to the inherent topology of the bands, and that it is robust against disorder, which clarifies key open issues regarding the nature of supercurrents in topological insulators.
Josephson supercurrent through a topological insulator surface state.
TLDR
Direct evidence for Josephson supercurrents in superconductor (Nb)-topological insulator (Bi(2)Te(3))-superconductor electron-beam fabricated junctions is provided by the observation of clear Shapiro steps under microwave irradiation, and a Fraunhofer-type dependence of the critical current on magnetic field.
Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator.
TLDR
These results provide strong evidence that SmB6 can host topological surface states in a bulk insulating gap stemming from the Kondo effect, which can serve as an ideal platform for investigating of the interplay between novel topological quantum states with emergent effects and competing orders induced by strongly correlated electrons.
Evidence for an anomalous current-phase relation in topological insulator Josephson junctions.
TLDR
Interferometry studies of Josephson junctions and superconducting quantum interference devices incorporating topological insulator weak links find that the nodes in single-junction diffraction patterns and SQUID oscillations are lifted and independent of chemical potential.
Magnetoresistance Anomaly in Topological Kondo Insulator SmB6 Nanowires with Strong Surface Magnetism
Topological Kondo insulators (TKIs) are a new class of topological materials in which topological surface states dominate the transport properties at low temperatures. They are also an ideal platform
Topological surface state in the Kondo insulator samarium hexaboride.
TLDR
Thickness-dependent transport measurements on doped SmB6 are reported, and it is shown that magnetic and non-magnetic doping results in contrasting behaviour that supports the conclusion that SmB 6 shows virtually no residual bulk conductivity.
Observing Majorana bound states of Josephson vortices in topological superconductors
TLDR
The equations governing the dynamics of phase solitons (fluxons) in a Josephson junction in a topological superconductor are studied and it is shown that the fluxon will bind a localized zero energy Majorana mode and will consequently behave as a non-Abelian anyon.
Observation of the superconducting proximity effect in the surface state of SmB6 thin films
The proximity effect at the interface between a topological insulator (TI) and a superconductor is predicted to give rise to chiral topological superconductivity and Majorana fermion excitations. In
Additional energy scale in SmB6 at low-temperature
TLDR
The authors' high-resolution data provide insight into the electronic structure of SmB6, which reconciles many current discrepancies on this compound, and can be understood in terms of a suppressed Kondo effect at the surface.
Gate-tuned normal and superconducting transport at the surface of a topological insulator
TLDR
This work studies transport through superconducting junctions fabricated on thin Bi2Se3 single crystals, equipped with a gate electrode, to demonstrate how gated nano-electronic devices give control over normal andsuperconducting transport of Dirac fermions at an individual surface of a three-dimensional topological insulators.
