a, Sample micrograph. Scale bar, 5 μm. The current flow and four-terminal measurement configuration is indicated. b, Sample schematic of the double hBN-aligned device. c, Rxx as a function of density at T = 1.6 K. The moiré peaks of both top and bottom hBN are labelled accordingly, with the green arrows indicating the supermoiré peaks at low densities owing to double alignment. Temperature-dependent resistance measurements for decreasing densities at D = 0 V nm−1 (d) and 0.6 V nm−1 (e).
