Enhancement in optically induced ultrafast THz response of MoSe2MoS2 heterobilayer
Sunil Kumar, Arvind Singh, Sandeep Kumar +7
THz conductivity of large area MoS2 and MoSe2 monolayers as well as their vertical heterostructure, MoSe2MoS2 is measured in the 0.3-5 THz frequency range. Compared to the monolaye…
Photo-Seebeck effect in single-crystalline bismuth telluride topological insulator
Anand Nivedan, Arvind Singh, Sandeep Kumar +1
Bismuth telluride is a low energy bulk band-gap topological system with conducting surface states. Besides its very good thermoelectric properties, it also makes a very good candid…
Magnetic field-dependent resistance crossover and logarithmic to non-saturating magnetoresistance in topological insulator BiTe
Anand Nivedan, Kamal Das, Sandeep Kumar +4
We report a metal-insulator like transition in single crystalline 3D topological insulator Bi2Te3 at a temperature of 230K in presence of an external magnetic field applied normal…
