Fig. 4: Summary on nonreciprocal resistances for varying carrier density and temperature.
From: Zero-field chiral edge transport in an intrinsic magnetic topological insulator MnBi2Te4
a, b Carrier density dependent nonreciprocal resistance and longitudinal resistance of left edge and right edge of the sample. Red circle and curve show the nonreciprocal resistance, blue ones are for the longitudinal resistance, namely first order harmonic resistance. The green arrows indicate the carrier densities shown in Fig. 3d, e Measurements were taken with back gate fixed at 40 V. c Temperature dependent nonreciprocal resistance. Measurement was conducted with carrier density fixed at \(2.0\times {10}^{12}c{m}^{-2}\) at 0 T.
