Gate-tunable quantum oscillations in ambipolar Cd3As2 thin films
Yanwen Liu, Cheng Zhang, Xiang Yuan +9
Electrostatic doping in materials can lead to various exciting electronic properties, such as metal-insulator transition and superconductivity, by altering the Fermi level position…
Phenomenology of Andreev reflection from first-principles transport theory
Awadhesh Narayan, Ivan Rungger, Stefano Sanvito
We study Andreev reflection in normal metal-superconductor junctions by using an extended Blonder-Tinkham-Klapwijk model combined with transport calculations based on density funct…
Topological tuning in three-dimensional Dirac semimetals
Awadhesh Narayan, Domenico Di Sante, Silvia Picozzi +1
We study with first-principles methods the interplay between bulk and surface Dirac fermions in three dimensional Dirac semimetals. By combining density functional theory with the…
Proximity induced topological state in graphene
Igor Popov, Mauro Mantega, Awadhesh Narayan +1
The appearance of topologically protected states at the surface of an ordinary insulator is a rare occurrence and to date only a handful of materials are known for having this prop…
Single atom anisotropic magnetoresistance on a topological insulator surface
Awadhesh Narayan, Ivan Rungger, Stefano Sanvito
We demonstrate single atom anisotropic magnetoresistance on the surface of a topological insulator, arising from the interplay between the helical spin-momentum-locked surface elec…
Efficient spin injection and giant magnetoresistance in Fe/MoS/Fe junctions
Kapildeb Dolui, Awadhesh Narayan, Ivan Rungger +1
We demonstrate giant magnetoresistance in Fe/MoS/Fe junctions by means of \textit{ab-initio} transport calculations. We show that junctions incorporating either a mono- or a bi…
