The Hall resistivity ρyx and thermoelectric Hall coefficient αxy exhibit plateaus at the quantum limit, where electrons occupy only the zeroth Landau level. In this condition, quantum oscillation in the Seebeck coefficient Sxx?ρyxαxy is suppressed, and the massless fermions are transformed into a Fermi liquid system. We show that the Seebeck coefficient at the quantum limit is expressed by the harmonic sum of Fermi wavelength and thermal de Broglie wavelength scaled by magnetic length.Fermi LiquidsFermionsMagnetosConditionFermi WavelengthFermi-liquid SystemsHall CoefficientHall ResistivityLandau LevelsQuantum LimitQuantum OscillationsThermalThermoelectricSeebeck Coefficientjournal article10.1103/PhysRevB.106.L0813042-s2.0-85138171207
