Quantum interference of pseudospin-1 fermions
Adesh Singh, G. Sharma
Quantum interference is studied in a three-band model of pseudospin-one fermions in the lattice. We derive a general formula for magnetoconductivity that predicts…
Anomalous transport in pseudospin-1 fermions
Adesh Singh, G. Sharma
Electronic transport in the model of pseudospin-1 fermions with a finite gap is studied within the semiclassical Boltzmann approximation. We show that coupling of…
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…
STM/S study of electronic inhomogeneity evolution with gate voltage in graphene: role of screening and charge-state of interface defects
Anil Kumar Singh, Anjan Kumar Gupta
Evolution of electronic inhomogeneities with back-gate voltage in graphene on SiO was studied using room temperature scanning tunneling microscopy and spectroscopy. The reversa…
Reversible control of interface-water induced carrier density in graphene-on-SiO by thermal cycling under gate-voltage
Anil Kumar Singh, Anjan Kumar Gupta
A reversible handle on graphene carrier density, other than the gate electric field, is desirable for memory applications of graphene. Our experiments show that the commonly observ…
