Magneto-Transport and High-Resolution Angle-Resolved Photoelectron Spectroscopy Studies of Palladium Doped BiTe
Shailja Sharma, Shiv Kumar, Girish C. Tewari +5
We have performed magneto-transport and high-resolution angle-resolved photoelectron spectroscopy (ARPES) measurements on palladium (Pd) doped topological insulator PdBi$_{2}…
Fe3Se4: A Possible Ferrimagnetic Half-Metal?
Girish C. Tewari, Divya Srivastava, Reijo Pohjonen +4
Half-metallic ferromagnets show 100% spin-polarization at the Fermi level and are ideal candidates for spintronic applications. Despite the extensive research in the field, very fe…
Non-equilibrium restoration of duality symmetry in the vicinity of the superconductor-insulator transition
I. Tamir, A. Doron, T. Levinson +3
The magnetic field driven superconductor to insulator transition in thin films was theoretically analyzed via a vortex-charge duality transformation applied to the Hamiltonian. Vor…
A Direct Determination of the Temperature of Overheated Electrons in an Insulator
Tal Levinson, Adam Doron, Idan Tamir +2
Highly disordered superconductors, in the magnetic-field-driven insulating state, can show discontinuous current-voltage characteristics. Electron overheating has been shown to giv…
Finite Size Effect in Amorphous Indium oxide
Sreemanta Mitra, Girish C. Tewari, Diana Mahalu +1
We study the low temperature magneto-transport properties of several highly disordered amorphous Indium oxide(a:InO) samples. Simultaneously fabricated devices comprising a 2-dimen…
Negative Magnetoresistance in Amorphous Indium Oxide Wires
Sreemanta Mitra, Girish C Tewari, Diana Mahalu +1
We study magneto-transport properties of several amorphous Indium oxide nanowires of different widths. The wires show superconducting transition at zero magnetic field, but, there…
The effects of competing magnetic interactions on the electronic properties of CuCrS2 and CuCrSe2
Girish C Tewari, T S Tripathi, A K Rastogi
We present a detail study of the electrical resistivity, thermoelectric power, magnetic susceptibility \c{hi} and the heat capacity CP in antiferromagnetic layered compounds CuCrS2…
Effect of chromium disorder on the thermoelectric properties of Layered-antiferromagnet CuCrS2
Girish Chandra Tewari, Tripurari Sharan Tripathi, Ashok Kumar Rastogi
Layered-antiferromagnetic compound CuCrS2 has been prepared by different methods. The analysis of X-ray diffraction patterns of different samples gave significant amount of vacancy…
Transport properties of Layer-Antiferromagnet CuCrS2: A possible thermoelectric material
G. C. Tewari, T. S. Tripathi, A. K. Rastogi
The electrical, thermal conductivity and Seebeck coefficient of the quenched, annealed and slowly cooled phases of the layer compound CuCrS2 have been reported between 15K to 300K.…
