Extended Data Fig. 1: Residual resistivity ratio and quantum oscillations.

a, Temperature dependent resistivity at zero magnetic field. The residual resistivity ratio (RRR) between 300 Kand 2 K is approximately 2000, signifying the high quality of the single crystal. b, Magnetic field (applied along the ĉ-axis) dependent resistivity showing Shubnikov-de Haas oscillations at 2 K. c, The fast Fourier transform (FFT) of the background-subtracted data of (b) when plotted against the inverse of the magnetic field. We notice four fundamental peaks corresponding to the extremal orbits of the electron and hole pockets in the Brillouin zone²⁴.
