a,b, VGate-dependent dI/dV spectrum taken from an old MATTG device, which is device #3 with twist angle θ = 1.51° at T = 0.4 K (a) and T = 7 K (b) highlighting diminishing zero-bias feature at 7 K. c, Linecut taken from a, where three clear peaks coexist at the same doping, at which the Kondo resonance is pinned to the Fermi level, compared with split flat band peaks that shift with doping. d,e, VGate-dependent dI/dV spectrum on area θ = 1.51° at T = 2 K (d) and T = 10 K (e) highlighting diminishing zero-bias feature at 10 K. f, VGate-dependent dI/dV spectrum on area θ = 1.43° at T = 2 K showing zero-bias peak along with split flat band peak on both positive and negative energies. g, VGate-dependent dI/dV spectrum on MATBG device with θ = 0.97° at T = 2 K showing zero-bias peak along with split flat band peak on both positive and negative energies.
