a, Hall resistance \({R}_{xy}\) as a function of the out-of-plane magnetic field \({B}_{\perp }\) measured at \({n}_{{\rm{e}}}=0.19\times {10}^{12}{{\rm{cm}}}^{-2}\), \(D=-0.4\) V/nm. b, Same measurement at \({n}_{{\rm{e}}}=0.43\times {10}^{12}{{\rm{cm}}}^{-2}\), \(D=0.38\) V/nm with a 0.1T in-plane magnetic field applied. The curves measured at different temperatures are offset by 200Ω for clarity. The Hall resistance was obtained by measuring the four-terminal resistance in two configurations and applying the Onsager reciprocal relation9.
