Abstract:Spin-polarized electrons can improve
the efficiency and
selectivity
of photo- and electro-catalytic reactions, as demonstrated in the
past with magnetic or magnetized catalysts. Here, we present a scheme
in which spin-polarized charge separation occurs at the interfaces
of nonmagnetic semiconductors and molecular films in the absence of
a magnetic field. We take advantage of the spin-valley-locked band
structure and valley-dependent optical selection rule in group VI
transition metal dichalcogenide (TMDC) mono… Show more
