Extended Data Fig. 1: Optical microscope images and two-terminal conductance of the tMBG devices.
From: Electrically tunable correlated and topological states in twisted monolayer–bilayer graphene
(a-d), the twist angle of each device is denoted at the bottom left corner of each image. All scale bars are 5 μm. (e-f) show the two-terminal conductance measured between neighbouring pairs of contacts as indicated by the colour-coded bars in (a-b). Device D1 exhibits a small twist angle gradient of approximately 0.03° primarily along the longitudinal direction of the Hall bar. Device D2 exhibits a larger twist angle inhomogeneity of approximately 0.1°, consistent with the apparent doubling of some of the transport features in Fig. 4a of the main text.
