Superconductors with non-trivial band topology are emerging as one of the best avenues to study quantum anomalies and experimental realization of Majorana Fermions. This article reports the successful crystal growth of superconducting SnAs, which can have topologically nontrivial states, as evidenced in DFT (Density Functional Theory) calculations, Z2 invariants and topologically surface state. Here, we followed a two-step method to grow SnAs crystal. The powder XRD (X-ray Diffractometry…

Electronic band structure and superconducting properties of SnAs
We report comprehensive study of physical properties of the binary superconductor compound SnAs. The electronic band structure of SnAs was investigated using both angle-resolved photoemission
SnAs with the NaCl-type Structure: Type-I Superconductivity and Single Valence State of Sn
We examined the superconductivity of SnAs and the valence state of Sn in its lattice with an expectation that SnAs and related compounds with the NaCl-type structure might exhibit superconductivity
Topological Superconductivity in CuxBi2Se3
A topological superconductor (TSC) is characterized by the topologically-protected gapless surface state that is essentially an Andreev bound state consisting of Majorana fermions. While a TSC has
Dirac surface states and nature of superconductivity in Noncentrosymmetric BiPd
While the superconducting state of BiPd appears topologically trivial, consistent with Bardeen–Cooper–Schrieffer theory with an order parameter governed by a single isotropic s-wave gap, it is shown that the material exhibits Dirac-cone surface states with a helical spin polarization.
Ni-doped Bi0.5Sb1.5Te3 single crystal: a potential functional material for thermoelectricity, topological insulator, and optoelectronics
We report the growth of Ni-doped Bi0.5Sb1.35Ni0.15Te3 single crystal via the self-flux method. The crystalline nature of a grown single crystal was confirmed by the X-ray diffraction technique (XRD).
Introduction to topological superconductivity and Majorana fermions
This short review paper provides a pedagogical introduction to the rapidly growing research field of Majorana fermions in topological superconductors. We first discuss in some detail the simplest
