a, b, Optical images of device A (presented in the main manuscript) (a) and device B (b). The top hBN is encircled in grey, the upper graphite flake in green, the upper hBN flake in red, the graphite contacts in pink, the bilayer graphene flake in blue, the lower hBN flake in yellow, and the lower graphite flake in purple. c, Schematic of the bilayer graphene devices. The colours of different flakes match those in a, b.
