Pseudospin-valve effect on transport in junctions of three-dimensional topological insulator surfaces

Pseudospin-valve effect on transport in junctions of three-dimensional topological insulator surfaces

We show that the surface states of pristine 3D topological insulators (TIs) are analogs of ferromagnetic half metals due to complete polarization of an emergent momentum independent pseudospin (SU(2)) degree of freedom on the surface. To put this claim on firm footing, we present results for TI surf...
