a Transverse thermopower Syx as a function of magnetic field at different temperatures. b Thermoelectric Hall conductivity \(\alpha _{xy}\) as a function of magnetic field at different temperatures. The peak value is caused by the finite scattering effect. c Thermoelectric Hall conductivity \(\alpha _{xy}\) as a function of temperature at various fields. The inset shows a linear behavior of \(\alpha _{xy}\) versus T at low temperatures. d \(\alpha _{xy}/T\) as a function of magnetic field at various temperatures. e An extrapolation of d showing a convergence to the quantized value at low temperatures. f The density of states (DOS) of each Landau level (LL), highlighting the unique n = 0 LL in a WSM. At high-enough B, n = 0 LL drives the DOS ∝ B.
