Misfit Layer Structures

The incommensurate composite structures consists of misfit layer structures, intergrowth compounds, Vernier structures and chimney-ladder structures [1 - 3]. In the investigation of complex misfit structures, the electron diffraction observation in TEM is very important since it usually shows the presence of satellite reflections which are often too weak to be seen in X-ray diffraction patterns. Powder X-ray diffraction, due to the typical preferential orientation of the misfit compounds, gives a very partial information of the samples.
