Quantum oscillation study of the large magnetoresistance in Mo substituted WTe single crystals
Sourabh Barua, M. R. Lees, G. Balakrishnan +1
The list of interesting electrical properties exhibited by transition metal dichalcogenides has grown with the discovery of extremely large magnetoresistance (MR) and type-II Weyl…
Quantum oscillations with non-zero Berry phase from a complex three dimensional Fermi surface in Bi2Te3
Sourabh Barua, K. P. Rajeev
We performed angle dependent magnetoresistance study of a metallic single crystal sample of Bi2Te3. We find that the magnetoresistance is highly asymmetric in positive and negative…
Evidence for topological surface states in metallic single crystals of Bi2Te3
Sourabh Barua, K. P. Rajeev, Anjan K. Gupta
Bi2Te3 is a member of a new class of materials known as topological insulators which are supposed to be insulating in the bulk and conducting on the surface. However experimental v…
Many Topological Insulators Fail the Surface Conduction Test
Sourabh Barua, K. P. Rajeev
In this report, we scrutinize the thickness dependent resistivity data from the recent literature on electrical transport measurements in topological insulators. A linear increase…
