Withers, Raymond2015-12-132015-12-130044-2968http://hdl.handle.net/1885/79959A review of the application of electron microscopy to disordered materials exhibiting sharp, highly structured diffuse intensity distributions is given from a modulation wave approach perspective. Structurally useful diffraction phenomena such as polarization, overall diffuse distribution shape and pseudo-extinction conditions are highlighted. The dangers of multiple scattering are emphasized before two particular such systems, substitutionally disordered solid solutions and inherently flexible framework structures are considered in more detail.Keywords: Diffuse scattering; Disordered materials; Displacive disorder; Electron microscopy; Substitutional disorder200510.1524/zkri.2005.220.12_2005.10272015-12-11
