Large Spin-Valley Polarization in Monolayer MoTe 2 on Top of EuO(111)

The electronic properties of monolayer MoTe 2 on top of EuO(111) are studied by first-principles calculations. Strong spin polarization is induced in MoTe 2 , which results in a large valley polarization. In a longitudinal electric field this will result in a valley and spin-polarized charge Hall effect. The direction of the Hall current as well as the valley and spin polarizations can be tuned by an external magnetic field.
