Photo- and exchange-field controlled line-type resonant peaks and enhanced spin and valley polarizations in a magnetic WSe2 junction

Mohammad Alipourzadeh et al.

Summary: This study investigates the transport properties of a normal/ferromagnetic/normal WSe2 junction with large incident angles. The transmission shows a gap with optically controllable width in a certain range of gate voltage, and the spin and valley resolved transmissions exhibit oscillatory behavior with respect to the gate voltage. By applying off-resonance light or exchange field, a switchable perfect spin and valley polarizations at all incident angles are found. For large incident angles, the transmission resonances change to spin-valley-dependent separated ideal line-type resonant peaks, resulting in switchable perfect spin and valley polarizations. Additionally, even in the absence of gate voltage, applying off-resonance light or exchange field at large incident angles can give spin-valley dependent ideal transmission peaks, making them capable of providing a switchable fully spin-valley filtering effect. These findings suggest alternative methods for high efficiency spin and valley filtering devices based on WSe2.

Spin-valley dependent Klein tunneling and perfect spin- and valley-polarized transport in a magnetic WSe2 superlattice

Yaser Hajati et al.

Summary: The study demonstrates the spin and valley transport through a magnetic WSe2 superlattice with off-resonance circularly polarized light and gate voltage. By increasing the number of barriers, optically and electrically tunable spin-valley dependent transmission gaps and transmission resonances can be observed. A perfect spin-and valley-polarized current can be obtained, which is tunable and switchable using an exchange field, off-resonance light, and gate voltage.

Spin- and valley-polarized transport and magnetoresistance in asymmetric ferromagnetic WSe2 tunnel junctions

Yaser Hajati et al.

Summary: The study demonstrates that the magnetic tunnel junction setup involving WSe2 exhibits adjustable spin and valley polarization properties under off-resonance light, leading to fully spin and valley-polarized current. Furthermore, the tunneling magnetoresistance (TMR) can be tuned to 1 by off-resonance light, highlighting the promising potential of WSe2 in magnetic memory and spin and valleytronics devices.
