Extended Data Fig. 2: Atomic structure and differential charge density calculated for the SnS2/WSe2 heterobilayer.
From: High-order superlattices by rolling up van der Waals heterostructures
a, TEM image of the SnS2/WSe2 heterobilayer. The moiré pattern shows a lattice constant of 3.34 nm, and the lattice consists of 10 × 10 WSe2 and 9 × 9 SnS2. Scale bar, 2 nm. b, c, Top (b) and side (c) view of the atomic structure and the differential charge density calculated for the SnS2/WSe2 heterobilayer. The amaranth and blue isosurfaces represent negative and positive charge density difference, respectively, between the bilayer vdW heterostructure and the separated layers. The isosurface value is chosen as 0.0005e au−3.
