Monolayer graphene with an energy gap presents a pseudospin symmetry broken ferromagnet with a perpendicular pseudomagnetization whose direction is switched by altering the type of doping between n and p. We demonstrate an electrical current switching effect in pseudospin version of a spin valve in which two pseudoferromagnetic regions are contacted through a normal graphene region. The proposed structure exhibits a pseudomagnetoresistance, defined as the relative difference of resistances of…

Abstract Transmission of massive Dirac fermions in a monolayer-gapped-graphene PF/N/PF pseudo spin valve is investigated where PF is a pseudo ferromagnet caused by gap opening in graphene and N is a
Photon-mediated interaction of pseudospins in graphene
The concept of pseudospins in graphene was previously introduced in order to describe the electron motion near the high-symmetry point of the Brillouin zone. Many physical properties are related to
Quantum pumping of layer pseudospin current in biased bilayer graphene
In bilayer graphene, the top layer and the bottom layer can be regarded as a kind of 'pseudospin'. By applying a voltage bias between the two layers, the pseudospin is polarized along the direction
Gate control of lattice-pseudospin currents in graphene on SW2: Effect of sublattice symmetry breaking and spin–orbit interaction
Strong spin–orbit interaction (SOI) in graphene grown on tungsten disulfide (SW2) has been recently observed, leading to energy gap opening by SOI. Energy gap in graphene may also be induced by

Abstract The tight-binding electrons in graphene grown on top of hexagonal boron nitride (h-BN) substrate are studied. The two types of surfaces on the h-BN substrate give rise to Dirac fermions

Abstract We study spin-valley and lattice-pseudospin currents in a dual ferromagnetic-gated silicene-based junction. Silicene has buckled atomic structure which allows us to take sublattice-dependent
