Prince Sharma, M. M. Sharma, Kapil Kumar +2
The topological behavior of heavy metal alloys opens a vast area for incredible research and future technology. Here, we extend our previous report about the superconducting proper…
High Field Magneto-Transport of Mixed Topological Insulators Bi2Se3-xTex (x = 0, 1, 2 & 3)
Deepak Sharma, Yogesh Kumar, P. Kumar +3
The article comprises structural, microstructural, and physical properties analysis of Bi2Se3-xTex (x= 0, 1, 2 and 3) mixed topological insulator (MTI) single crystals. All the cry…
Metal Doping in Topological Insulators- A Key for Tunable Generation of Terahertz
Prince Sharma1, M. M Sharma, Mahesh Kumar +1
The unique surface edge states make topological insulators a primary focus among different applications. In this article, we synthesized a large single crystal of Niobium(Nb)-doped…
Type-II Superconductivity below 4K in Sn0.4Sb0.6
M. M. Sharma, Kapil Kumar, Lina Sang +2
In this article, we report the occurrence of superconductivity in Sn0.4Sb0.6 single crystal at below 4K. Rietveld refined Powder XRD data confirms the phase purity of as grown crys…
Crystal Growth and characterization of possible New Magnetic Topological Insulators FeBi2Te4
Ankush Saxena, Poonam Rani, S. Patnaik +3
Here we report successful single crystal growth of new possible magnetic topological insulator (MTI) FeBi2Te4 by self-flux method via vacuum encapsulation process. The detailed Rie…
Exploration of terahertz from time-resolved ultrafast spectroscopy in single-crystal Bi2Se3 topological insulator
Prince Sharma, Mahesh Kumar, V. P. S. Awana
In this article, we reconnoiter the differential reflection signal of a Bi2Se3 single crystal flake, using ultrafast transient absorption spectroscopy in the femtosecond time domai…
