Superconducting hybrid structures with topological order and induced magnetization offer a promising way to realize fault-tolerant quantum computation. However, the effect of interplay between property insulator surface, otherwise known as spin-momentum locking on superconducting proximity effect, still remains be investigated. We relied quasiclassical self-consistent approach consider transiti...

One-dimensional systems proximity-coupled to a superconductor can be driven into topological superconducting phase by an external magnetic field. Here, we investigate the effect of vortices created field in type-II providing proximity effect. We identify different ways which protection Majorana modes compromised and discuss strategies circumvent these detrimental effects. Our findings are also ...

A heterostructure consisting of a topological insulator (TI) nanowire brought into proximity with superconducting layer provides promising route to achieve superconductivity and associated Majorana bound states (MBSs). Here, we study effects caused by such coupling between thin an $s$-wave superconductor TI nanowire. We show that there is distinct phenomenology arising from the metallization in...

We synthesize the Weyl semimetal/superconductor NbP/NbSe 2 composite and observe stable bulk superconductivity at T c = 7.2, 6.9, 6.8 K for NbSe crystal, (1:1), (2:1) composites, respectively, despite large volume fraction of non-superconducting NbP phase. From Ginzburg–Landau theory, H c2 (0) is significantly enhanced in composites [22 (1:1) 18.5 (2:1)] comparing with pristine crystal (8 T). T...

The proximity effect between a superconductor and a highly diffusive two-dimensional metal is revealed in a scanning tunneling spectroscopy experiment. The in situ elaborated samples consist of superconducting single crystalline Pb islands interconnected by a nonsuperconducting atomically thin disordered Pb wetting layer. In the vicinity of each superconducting island the wetting layer acquires...

The effect of smooth inhomogeneities near a superconductor boundary on the magnetic penetration depth λ is studied with emphasis on the proximity-induced spatial dependence of the Cooper pair amplitude. The influence of surface pair breaking or pair formation on λ is described within the Ginzburg-Landau theory, with no model assumptions, for both strongly type-II and strongly type-I homogeneous...
