In this paper, Meetsma, Wiegers, Haange & de Boer used high-resolution imaging to study the remarkable incommensurable misfit layer compound (SnS)1.17NbS2, 'SnNbStS3'.Abstract:
Electron diffraction and high-resolution imaging are used to study the remarkable incommensurable misfit layer compound (SnS)1.17NbS2, 'SnNbS3'. Electron diffraction patterns along the zone axis perpendicular to the layer planes are analysed in detail based on the mixed-layer assumption proposed in paper I [Meetsma, Wiegers, Haange & de Boer (1989). Acta Cryst. A45, 285-291]. The relative intensities of the hk0 reflections due to the two types of constituent layers are strongly influenced by the foil thickness. Stacking variants along the c axis are frequently observed and strongly complicate the diffraction patterns. Under particular conditions of thickness and defocus, high-resolution images are shown to reflect the varying degree of coincidence of the atom columns in the misfit layers and thus they directly reveal the incommensurate misfit.read more

Incommensurate misfit layer compounds of the type “MTS3” (M = Sn, Pb, Bi, rare earth elements; T = Nb, Ta): A study by means of electron microscopy
TL;DR: In this article, it is shown how high resolution images in the layer plane directly reveal the incommensurate misfit through the varying coincidence of the atom columns of the two substructures.
