(color online) The gate voltage modulated magnetotransport at 1.5 K. (a) The MR and Hall resistance of the 80-nm sample. (b) The Landau plot of the SdH oscillations, indicating the nontrivial Berry phase. The inset represents the Landau levels at different gate voltages. (c) and (d) The p-type gate effect of MR and the Hall resistance at different magnetic field strengths for the 31-nm sample. |
