(e,f) High-resolution atomic lattice images acquired from the island and the base regions from b, together with the corresponding Fourier transform patterns. Although the outline of moire´ pattern becomes slightly vague, the hexagonal lattice structure of graphene remains almost intact in the ...
This moiré pattern can be tuned by the relative intensity of the interfering light beams and rotation angle between the mask patterns. “Our work was inspired by the ‘magic’ angle in bilayer graphene,” Ye says. “We wondered, how will light waves respond if we stack two optical lattices...

Now another chapter is being added to this field of research: If two such 2D layers are stacked at the right angle, even more new possibilities arise. The way in which the atoms of the two layers interact creates intricate geometric patterns, and these patterns have a decisive impact on the...

We study the effect of atomic relaxation on the structure of moiré patterns in twisted graphene on graphite and double layer graphene by large scale atomistic simulations. The reconstructed structure can be described as a superlattice of 'hot spots' with vortex-like behaviour of in-plane ...
