Extended Data Fig. 5: Additional temperature dependence data of the correlated insulator.
From: Correlated insulator and Chern insulators in pentalayer rhombohedral-stacked graphene
a, Temperature dependence of the four-probe resistance Rxx measured at charge neutrality (n = 0). BI and CI stand for band insulator and correlated insulator. The correlated insulator develops below ~ 30 K. The two white arrows indicate the semimetal phase with an anomalous temperature dependence at the low-temperature region, discussed in Fig. 4c. b, Rxx versus D at even higher temperatures. As the temperature is increased, the resistive state at D = 0 disappears and evolves to a dip in Rxx. Circles trace the center of the bumps in Rxx.
