Extended Data Fig. 3: VGate switching of dI/dV spectrum owing to intervalley coherence reconstruction.
From: Resolving intervalley gaps and many-body resonances in moiré superconductors
a, VGate-dependent dI/dV spectroscopy focusing on the hole-doping side, in which we observe correlated gap. Red (green) dashed line indicates VBias at which c (d) is taken. b, Tip height as a function of VGate recorded for this figure. Tunnelling current feedback is turned ON, which gives smooth increasing background in height. c, Tunnelling dI/dV as a function of VGate for fixed VBias = −3 mV after 5 mins of taking data in a. The position of the dI/dV peak in VGate matches the VGate at which switching happens in a around −8.5 V, indicating that certain switching behaviours seen in VGate-dependent spectroscopies are reproducible over measurements taken at different times. d, Tunnelling dI/dV as a function of VGate for fixed VBias = 3 mV after 2 mins of taking data in c.
