Spin Polarized Transport

We theoretically investigate the electron transport properties in a nanostructure modulated by a ferromagnetic stripe (FM) and a Schottky metal stripe (SM) as well as a [Formula: see text]-doping with the help of transfer-matrix method. It is found that the position and the weight of the [Formula: see text]-doping, the width of the SM and the electrical potential, all play an important role in the electron transmission probability and the spin polarization. Therefore, we can control the electron transport properties through adjusting the SM and the [Formula: see text]-doping. These interesting phenomena may be very helpful for designing the spintronic devices.

Based on MoC2 nanoribbons and poly-(terphenylene-butadiynylene) (PTB) molecules, we designed MoC2-PTB molecular spintronic devices and investigated their spin-dependent electron transport properties by using spin-polarized density functional theory and non-equilibrium Green's...

Spin Polarized Transport

Electronic, magnetic and spin-polarized transport properties of the zigzag-zigzag pentagraphene nanoribbon are investigated theoretically within the framework of density functional theory combined with non-equilibrium Green’s function formalism. It is found that the spinunpolarized ZZ-PGNR behaves as metal. However, the spin-polarized ZZ-PGNRs show to be the magnetic semiconductor properties. More importantly, for the ZZ-PGNRs based device, the spin-filtering effect occurs strongly near Fermi level. Our findings suggest that ZZ-PGNRs might hold a significant promise for developing spintronic devices.
