Spin Caloritronic Transport of （2×1） Reconstructed Zigzag MoS₂ Nanoribbons

【摘要】 Using first-principles density functional theory combined with nonequilibrium Green’s function method, we investigate the spin caloritronic transport properties of（2×1） reconstructed zigzag MoS₂ nanoribbons. These systems can exhibit obvious spin Seebeck effect. Furthermore, by tuning the external magnetic field, a thermal giant magnetoresistance up to 10⁴% can be achieved. These spin caloritronic transport properties are understood in terms of spin-resolved transmission spectra, band structures, and the symmetry analyses of energy bands around the Fermi level.更多还原
