Probing of large interfacial contribution to spin orbit coupling in CoFeB/Ta heterostructure by ultrafast THz emission spectroscopy
Sandeep Kumar, Sunil Kumar
Ultrafast THz radiation generation from ferromagnetic/nonmagnetic bilayer heterostructure-based spintronic emitters generally exploits the conversion from spin- to charge-current w…
Sub-bandgap activated charges transfer in a graphene-MoS2-graphene heterostructure
Sunil Kumar, Arvind Singh, Anand Nivedan +7
Monolayers of transition metal dichalcogenides are semiconducting materials which offer many prospects in optoelectronics. A monolayer of molybdenum disulfide (MoS2) has a direct b…
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…
