Electronic structure and Magneto-transport in MoS${}_2$/Phosphorene van der Waals heterostructure

Abstract

The time-dependent spin current mediated spin transfer torque behaviour has been investigated via scattering formalism within density functional theory framework supported by Green's function. Quantum magnetotransport characteristics have been revealed in a model semiconducting MoS${}_2$/phosphorene van der Waals heterostructure. The dynamics of spin current channelized heterolayer transport has been studied with rotational variation in magnetization angle. It is observed that the time-dependent spin transport torque remains invariant irrespective of magnetization angle direction. The polarized spin-current is persistent with the external magnetic field for potential applicability towards spintronics.
