This is useful for investigating discrete nanoparticles or localised regions such as interfacial layers. Nanobeam diffraction uses a very fine parallel probe of just a few namometres to generate diffraction information. There are a number of more specialised electron diffraction techniques. The limited accuracy and precision of electron diffraction when compared with X-ray diffraction for example, makes it difficult to identify phases with diffraction alone, in the absence of supporting information like composition. Generally, one already knows a great deal about the material before carrying out diffraction. Here the ring radii may be converted into d-spacings.Įlectron diffraction is a powerful adjunct to the imaging and spectroscopy capabilities of a TEM. Where polycrystalline materials are examined, ring diffraction patterns are obtained. a precipitate within a matrix), then the composite pattern arising from the two lattices can be used to determine the orientation relationship between the phases. Where two phases are selected by the aperture (e.g. The separation of the spots can be used to determine the d-spacing of the crystal (with an accuracy of about 1 %) and the angles between, and the relative spacings of, the spots can be used to determine the zone axis of the crystal. Single crystal regions of specimen, where the electron beam lies parallel to a low index crystallographic direction will result in simple spot patterns. Putting the microscope into diffraction mode results in a pattern being displayed on the screen. This may be as small as 0.5 µm in diameter. Here an aperture is used to select the region of interest. The most frequently used diffraction mode on a transmission electron microscope (TEM) is selected area diffraction. This results in the formation of patterns wherein the symmetries and intensities provide information on the crystalline structure of the material.
