Extended Data Fig. 5: Possible weak superconductivity at 1/2 filling.

Vxx and dVxx/dI as a function of the d.c. bias current at a hole-doped 1/2-filling state. The narrow plateau in the I–V curve and the dip of dVxx/dI near zero bias current may be due to very weak superconductivity in this state. Data are taken at T = 0.04 K.
