Growth, Characterization and High Field Magneto-Conductivity of Co0.1Bi2Se3 Topological Insulator
Rabia Sultana, Ganesh Gurjar, S. Patnaik +1
We report the crystal growth as well as transport properties of Co added Bi2Se3 single crystals. The values of the lattice parameters a and b for Co added sample were observed to i…
Multi-band superconductivity driven by a site-selective mechanism in MoGa
Anshu Sirohi, Surabhi Saha, Prakriti Neha +4
The family of the endohedral gallide cluster compounds recently emerged as a new family of superconductors which is expected to host systems displaying unconventional physics. Mo$_…
Suppression of transport spin-polarization of surface states with emergence of ferromagnetism in Mn-doped Bi2Se3
Suman Kamboj, Shekhar Das, Anshu Sirohi +5
The surface states of topological insulators (TI) are protected by time reversal symmetry and they display intrinsic spin helicity where the momentum of the charge carriers decides…
High Field Magneto-Conductivity Analysis of Bi2Se3 Single Crystal
Rabia Sultana, Ganesh Gurjar, S. Patnaik +1
We report the high field (up to 14Tesla) magneto-conductivity analysis of Bi2Se3 topological insulator grown via the self flux method. The detailed experimental investigations incl…
Low-energy excitations and non-BCS superconductivity in Nb-BiSe
Anshu Sirohi, Shekhar Das, Prakriti Neha +3
When certain elemental metals like Cu, Sr and Nb are intercalated between the layers of BiSe, a topological insulator, the intercalated systems superconduct with critical t…
Direct Evidence for Time-Reversal Symmetry Breaking in Topological Superconductor Sr0.1Bi2Se3
P. Neha, P. K. Biswas, Tanmoy Das +1
The single helical Fermi surface on the surface state of three-dimensional topological insulator Bi2Se3 is constrained by the time-reversal invariant bulk topology to possess a spi…
