Spin-dependent polarization and quantum Hall conductivity in decorated graphene: influence of locally induced spin-orbit-couplings and impurities

Author(s): Belayadi A; Vasilopoulos P;

We study spin transport through graphene-like substrates in the presence of one or several, locally induced spin-orbit coupling (SOC) terms resulting from periodically placed strips, on their top and decorated with a random distribution of impurities. Intrinsic SOC (ISOC), Rashba SOC (RSOC) and/or pseudo-spin-inversion-asymmetry coupling (PIAC) are consid ...

A spin modulating device, tuned by the Fermi energy, in honeycomb-like substrates periodically stubbed with transition-metal-dichalkogenides

Author(s): Belayadi A; Vasilopoulos P;

We investigate spin transport through graphene-like substrates stubbed vertically with transition-metal-dichalkogenides (TMDs). A tight-binding model is used based on a graphene-like Hamiltonian that includes di?erent types of spin-orbit coupling (SOC) terms permitted by the C3v symmetry group in TMDs/graphene-like heterostructures. The results show a spi ...
