Abstract The switching mechanisms of a spin current diode induced by an alternating electric field are investigated within fully epitaxial magnetic tunnel junctions (TJs) composed SiC double layer. This is achieved through precise engineering the spatial positions Co atoms, which spin‐diode tunneling process, driven bias voltage (BV), carefully explored. work reveals that incorporating high‐spin atoms into SiC‐Co junction forms spin‐down domain wall, thereby facilitating filtering....
Topological superconductors (TSCs) are an exotic field due to the existence of Majorana zero-modes (MZM) that obey non-Abelian statistics and can be used implement topological quantum computations.
We have successfully predicted the local topological bands in frustrated kagome lattice SbV3S5. An important future research direction is to raise band with novel co-existing strong nonlinear dispersion and cohesion due anisotropic inner field of SbV3S5 Fermi level. The Z2 index T-invariant systems provides evidence for a σyz near level that determines quantum anomalous Hall state. This shows effect (QAHE) phase has weak stability sensitive disorder interactions. Neighbouring van Hove...
We conducted first-principles calculations to investigate the dynamic braiding of local edge states and spin topological transport mechanism in a strong MoS1.75Te0.25 matrix. The presence type-II Van Hove singularity middle X-S path indicates cohesive interaction paring condensation within surface state data clearly demonstrate characteristic features regular loop transport. Hall conductivity matrix was determined from anisotropic characteristics Berry curvature. phase transition evidenced...
Analyse small polaron itinerant conductivity by the Fermi surfaces (FS) and spin texture will give insight on AHC transport characteristics.
Abstract Understanding electron quantum transport and their coupling interactions in 2D matrix is crucial for manipulating designing more efficient energy conversion devices, especially the context of spin transport. Here, we systematically calculate electronic dispersion properties which synergistic interaction three‐band accounted topological edge correlated electrons. The helical state protected by topology appears at boundary, accompanied upward movement (∼0.2 eV) point caused excitation...
Two-dimensional topological materials with flat bands and van Hove singularities in their electronic band structures are common, these features may lead to superconductivity due the strong condensation of states. However, electron–phonon coupling between single longitudinal acoustic (LA) phonons has not been extensively studied or reported. In this work, using group theory, symmetry analysis, first-principles calculations, we investigate electron bands, phonon spectra, a two-dimensional...
