Extended Data Fig. 4

a, SnS2/WSe2 heterobilayer FET. b, SnS2/WSe2 roll-up FET. The pink colour represents WSe2, yellow denotes SnS2 and gold represents the Cr/Au contact pads. c, d, Statistical distribution of mobility (c) and carrier concentration (d) of SnS2/WSe2 heterobilayer FETs and SnS2/WSe2 roll-up FETs. e, Normalized magnetoresistance of the roll-up vdW superlattices with different rotation angles θ at T = 3 K. Both the shapes and amplitudes overlap when the field is normalized to Bsinθ.
