Nonlinear Hall effect in Td-TaIrTe4 (IMAGE) Science China Press Caption (a), Optical image of 12-electrode device with active areas protected by h-BN; (b) the relationship between the first-order transverse Hall voltage and longitudinal voltage at 100 K and (c) the relationship between the second-order & third-order transverse nonlinear Hall voltage and longitudinal voltage at 100 K; (d) The relationship between the third-order transverse nonlinear Hall voltage and the longitudinal voltage measured at room temperature. All measured voltage signals in the transverse direction are perpendicular to the current direction, which is marked in (a). Credit ©Science China Press Usage Restrictions Use with credit.
