 abstract = {We study a junction of a topological insulator with a thin
two-dimensional nonmagnetic or partially polarized ferromagnetic
metallic film deposited on a three-dimensional insulator. We show, by
deriving generic boundary conditions applicable to electrons traversing
the junction, that there is a finite spin-current injection into the
film whose magnitude can be controlled by tuning a voltage V applied
across the junction. For ferromagnetic films, the direction of the
component of the spin current along the film magnetization can also be
tuned by tuning the barrier potential V-0 at the junction. We point out
the role of the chiral spin-momentum locking of the Dirac electrons
behind this phenomenon and suggest experiments to test our theory.},
