Abstract
The contrast observed in the [0001] HREM images of MoS2 are interprete d with a model based on rotational moire 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 th e experimental images. The calculations suggest that these rotations o ccur between the sulphur layers of the MoS2 structure. (C) 1998 Wiley- Liss, Inc.
