The paper deals with the properties of octagraphene nanoribbon determined in terms of the local spin density approximation and nonequilibrium Green’s function, namely transmission spectra, current–voltage characteristics (I–V curves), and differential conductivity of the zigzag-edged octagraphene nanoribbon obtained after the removal of carbon atoms from its center and saturation with hydrogen atoms. The I–V curves are characterized by a section with negative differential resistance caused by the resonant-tunneling of quasiparticles. The dI/dV curve shows similar changes. It is found that in the zigzag-edged octagraphene nanoribbon (with the network consisting of hexagons and a carbon bridge), spin-down quasiparticles are blocked in the energy range from –1.65 to –0.5 eV. This behavior of the transmission spectrum allows octagraphene nanoribbons to be applied in creation of energy spin filters. It is shown that the spin-polarized current in zigzag-edged octagraphene nanoribbon (with the network consisting of pentagons and a carbon bridge) with spin-up quasiparticles significantly exceeds the current in that with spin-up and spin-down quasiparticles. This effect allows the selection of spin-up quasiparticles at a certain voltage applied. The obtained results can be useful in the new developments of spintronic devices.
