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…
Andreev reflection spectroscopy on SnAs single crystals
Sandeep Howlader, Nikhlesh Mehta, M. M. Sharma +2
Binary compounds of SnT family(T= As, Sb, Te, S, Se, P) exhibit novel properties like superconductivity, topologically protected states etc. Some of these compounds crystallize in…
Accessing Phase Slip Events in Nb Meander Wires
Deepika Sawle, Sudhir Husale, Sachin Yadav +3
We report transport studies through Nb-based superconducting meander wires fabricated by focused ion beam (FIB) milling technique. The effect of meandering on quantum transport has…
SnAs: a 4K weak type-II superconductor with non-trivial band topology
M. M. Sharma, N. K. Karn, Prince Sharma +3
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 re…
Structural and WAL analysis of Topological single-crystal SnSb2Te4
Ankush Saxena, M. M. Sharma, Prince Sharma +5
Here, we report successful single crystal growth of SnSb2Te4 using the self-flux method. Unidirectional crystal growth is confirmed through X Ray Diffraction (XRD) pattern taken on…
Probing the Topological Surface States through Magnetoresistance and Ultrafast Charge Carrier Dynamics in (Bi/Sb)2Te3
Prince Sharma, Yogesh Kumar, V. P. S. Awana +1
Topological insulators with their topological protected surface states are highly promising quantum materials. In this article the micro-flakes of single-crystalline topological in…
Superconductivity with Topological non-trivial surface states in NbC
N. K. Karn, M. M. Sharma, Prince Sharma +3
Quantum materials with non-trivial band topology and bulk superconductivity are considered superior materials to realize topological superconductivity. In this regard, we report de…
Modeling of Magneto-Conductivity of Bismuth Selenide -- A Topological Insulator
Yogesh Kumar, Rabia Sultana, Prince Sharma +1
We report the magneto-conductivity analysis of Bi2Se3 single crystal at different temperatures in a magnetic field range of 14Tesla. The single crystals are grown by the self-flux…
