Crystal structure of representative superlattices.
(a) top view of a superlattice as indicated by solid lines and its associated first Brillouin zone; side views of (b) the 1:1 superlattice where MoS2:WSe2 equals to 1:1; (c) the 2:1 superlattice where MoS2:WSe2 equals to 2:1; (d) the 5:1 monolayer superlattice where all MoS2 and WSe2 bilayers were replaced by the corresponding monolayers.
