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…
Stretching of BDT-gold molecular junctions: thiol or thiolate termination?
Amaury de Melo Souza, Ivan Rungger, Renato Borges Pontes +4
It is often assumed that the hydrogen atoms in the thiol groups of a benzene-1,4-dithiol dissociate when Au-benzene-1,4-dithiol-Au junctions are formed. We demonstrate, by stabilit…
Electronic and magnetic properties of Ti4O7 predicted by self-interaction corrected density functional theory
Xiaoliang Zhong, Ivan Rungger, Peter Zapol +1
Understanding electronic properties of sub-stoichiometric phases of titanium oxide such as Magnéli phase Ti4O7 is crucial in designing and modeling resistive switching devices. Her…
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…
Ab-initio transport across Bismuth Selenide surface barriers
Awadhesh Narayan, Ivan Rungger, Andrea Droghetti +1
We investigate the effect of potential barriers in the form of step edges on the scattering properties of BiSe(111) topological surface states by means of large-scale ab-in…
