Abstract：Using first-principles density functional theory combined with nonequilibrium Green's function method, we investigate the spin caloritronic transport properties of (2$\times$1) reconstructed zigzag MoS$_{2}$ nanoribbons. These systems can exhibit obvious spin Seebeck effect. Furthermore, by tuning the external magnetic field, a thermal giant magnetoresistance up to 10$^{4}$% 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.
