title: Moiré patterns in high resolution electron microscopy images of MoS2.
abstract: The contrast observed in the (0001) HREM images of MoS2 are interpreted with a model based on rotational moiré patterns. Computer-simulated images show that rotations of two supercells by angles of 3, 5, 8, and 16 degrees around their centers reproduce the contrast observed in the experimental images. The calculations suggest that these rotations occur between the sulphur layers of the MoS2 structure.
