Popis: In transition metal dichalcogenide monolayers, the spin and valley degrees of freedom are strongly coupled. Here, the authors engineer a WSe2/MoSe2 heterostructure in which inter-valley transitions of interlayer excitons exhibit a giant splitting and near-unity polarization in a magnetic field.
