Heatmap from Scientific Research

VPTE response near the CNP shows a characteristic six-fold symmetry, which confirms the thermoelectric origin of the response. Dashed lines in d and e are visual guides. Insets: linecuts of the dual gate map along the horizontal and vertical dashed lines, where one of the top gates is kept at neutrality. All gate voltage dependences are plotted as a function of the filling of the moire bands. This conversion is calculated using the carrier density at full filling and the gate capacitances, which are both extracted from magneto-transport data.
