From: Resolving intervalley gaps and many-body resonances in moiré superconductors
a, VGate-dependent dI/dV spectrum taken at T = 400 mK on the AAA site featuring correlated gaps on the electron-doped side. b,c, VGate-dependent dI/dV spectrum focusing between ν = 2 to 3 at out-of-plane magnetic field 0 T (b) and 600 mT (c). d, Intensity of the peaks at Kekulé reciprocal lattice vector normalized by the intensity of the peaks at graphene reciprocal lattice vector as a function of VGate. VBias at which the real-space dI/dV map is taken is chosen to be at the coherence peak of the gap. e, Tunnelling dI/dV spectrum as a function of temperature at fixed VGate = 10.7 V. f,g, Point-contact dI/dV spectrum showing weak Andreev reflection signal on the electron side.
