Extended Data Fig. 6: Angle-dependent SdHOs of the 2DHG and the 2DEG in BAs devices.

a, Angle-dependent Rxx versus B⊥ in the 2DHG with p = 7.14 × 1012 cm−2 (BAs-S2, Vg = −7 V), which barely shows any changes in the positions of the SdHO extrema. b, Angle-dependent Rxx versus B⊥ in the 2DEG with n = 3.95 × 1012 cm−2 (BAs-S9, Vg = 5 V), which also shows high agreement in SdHO peak positions. These results confirm that no Zeeman-splitting-induced LL crossing occurs within the experimental maximum B of 14 T. Note that Rxx data for different θ are offset for clarity. The measurement T is 1.6 K. See Supplementary Note 2 for detailed discussions.
