Fig. 2: Electrical transport and thermoelectric measurements of Co1/3NbS2.

a Temperature-dependent longitudinal and transverse resistivity. b Temperature-dependent Seebeck coefficient of Co1/3NbS2. The inset shows the optical image of the device used for electrical transport and thermoelectric measurements. The scale bar is 20 μm. The sign change in temperature of Sxx is indicated by the red arrow. c Nernst coefficient Sxy versus magnetic field at different temperatures. The temperatures are calibrated to be the actual temperature under the heating current. d Temperature-dependent Sxy of Co1/3NbS2. Open circles are experimental data. The solid blue line represents the best fit using the Mott relation with n = 2.22. The dashed green curve is the best fit with 0. All data were obtained after  ±4 T FC, followed by (anti)symmetrization processing.
