Anisotropy in Electronic and Magneto-transport of 2D superconductor NbSe
N. K. Karn, M. M. Sharma, I. Felner +1
This article reports the successful synthesis of single crystalline two-dimensional thin flakes of NbSe. The XRD pattern of the grown crystal ensured its crystallization in a s…
Superconductivity at 9 K in Pb-Bi Alloy
N. K. Karn, Kapil Kumar, Naveen Kumar +4
In the present work, we report the synthesis of Pb-Bi alloy with enhanced Tc of up to 9K, which is higher than that of Pb. The alloy is synthesized via a solid-state reaction route…
Synthesis of possible room temperature superconductor LK-99:PbCu(PO)O
Kapil Kumar, N. K. Karn, V. P. S. Awana
The quest for room-temperature superconductors has been teasing scientists and physicists, since its inception in 1911 itself. Several assertions have already been made about room…
Normal state magneto transport properties of FeSeTe superconductor: The role of topological surface states
N. K. Karn, M. M. Sharma, V. P. S. Awana
Doped Iron Chalcogenide (FeCh) superconductors are extensively studied in the context of topological superconductivity. However, the evidence of topological surface states in elect…
Topological Superconductor AuSn4: A first principle study
N. K. Karn, M. M. Sharma, V. P. S. Awana
Topological semimetals such as Weyl or Dirac semimetals with superconductivity have emerged as a new class of topological materials to realize and study Majorana Fermion. This arti…
Bulk superconductivity and non-trivial band topology analysis of Pb2Pd
M. M. Sharma, N. K. Karn, Poonam Rani +2
A perfect topological superconductor can be realized by the simultaneous existence of bulk superconductivity along with topological non-trivial surface states. In this article, we…
