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…
Bulk Superconductivity below 6K in PdBi2Te3 topological single crystal
M. M. Sharma, Lina Sang, Poonam Rani +2
We study the structural and bulk superconducting properties of self flux grown PdBi2Te3 single crystal. Phase purity of as grown crystal is confirmed by Rietveld refinement of gent…
Superconductivity below 2.5K in Nb0.25Bi2Se3 topological insulator single crystal
M. M. Sharma, P. Rani, Lina Sang +2
We report crystal growth and below 2.5K superconductivity of Nb0.25Bi2Se3. These crystals are grown by self flux method. The X-ray diffraction (XRD) pattern of as grown crystal fla…
Ultrafast Spectroscopy of Bi2Se3 Topological Insulator
P. Sharma, D. Sharma, N. Vashistha +4
We investigate the ultrafast transient absorption spectrum of Bi2Se3 topological insulator. Bi2Se3 single crystal is grown through conventional solid-state reaction routevia self-f…
