“…The band gaps of APNTs are larger than that of ZPNTs in the same diameter range. The band gaps of PNTs gradually increase as nanotube diameter increases, which is consistent with previous theoretical report photo-excitations [29][30][31]. Through the microscopic images describing the origin of the polarized photocurrent in figure 1(c), we can comprehend the diversification of the spin photoresponse.…”

We have investigated photon-assisted spin injection into blue phosphorene nanotubes (PNTs) with ferromagnetic cobalt electrodes by nonequilibrium Green’s function combined with light–matter interaction based on the first-order Born approximation. The results show the photo-induced spin current. The spin up and spin down photocurrents flow in opposite directions for zigzag blue nanotubes (ZPNTs) with anti-parallel magnetic configuration of the electrodes. By changing the structures of the blue phosphorene nanotube and the magnetization of the electrodes, multitudes of quantum spin transport properties are investigated, such as the nearly perfect photo-induced spin current and strong photo-polarization current signal. The results suggest that ZPNTs could serve as a potential material candidate for optical communication devices.

“…Both GDYNRs and GYNRs have unique electrical and optical properties that are strongly dependent on their chemical structure, particularly their width and edge configuration. [152][153][154][155][156][157][158][159][160][161][162][163][164] Therefore, the controllable synthesis of GYNRs and GDYNRs with precise chemical structure is of great significance for its basic research and device applications.…”

“…Tao et al demonstrated a new scheme for generating fully spin-polarized photocurrent by constructing a van der Waals h-BN/ZGNR/h-BN heterostructure [19]. Furthermore, the robust generation scheme of pure spin current by light irradiation in ZGNR-based devices has been well established [20,21]. However, most schemes have the same problem that the energy difference between the ferromagnetic (FM) and anti-FM (AFM) state in their adopted materials is negligibly small or even disappear, making the spin polarization and the generation of current virtually difficult to observe in the AFM state based on which desired spin polarization is predicted.…”

Based on ﬁrst-principle calculations combined with non-equilibrium Green’s function method, we investigate the spin-polarized transport properties of a two-probe device which consists of a vacuum barrier sandwiched between two semi-inﬁnite ferromagnetic zigzag graphene nanoribbons (ZGNRs). It is well known that any vacuum barrier itself is not spin-polarized, and meanwhile, the inﬁnite pristine ferromagnetic ZGNR presents no spin polarization in the transmission function around the Fermi level. However, our computational results indicate that robust large spin polarization is found in the proposed device. More interestingly, giant magnetoresistance up to 3.0 × 108% can be obtained at low bias voltage. Furthermore, the photogalvanic eﬀect (PGE)-induced fully spin-polarized photocurrent or pure spin photocurrent can be generated in such device by illumination with polarized light, depending on the symmetry of structure. Consequently, our results indicate that vacuum barrier may show interesting spin-polarized transport properties in certain systems and should be taken into consideration in the construction of molecular junctions and spintronic devices.
