Web electron diffraction, interference effects owing to the wavelike nature of a beam of electrons when passing near matter. The technique is usually performed in a transmitting electron microscope (tem), and scanning electron microscope (sem) as electron backscatter diffraction. Produced from diffraction of the electron beam off of planes in the sample. First we will discuss spot patterns and how. Planes that are spaced farther apart produce a narrower patterns. Web one of the capabilities of electron microscopes is to obtain diffraction patterns, which can be analyzed to give information about the structure of the specimen. Web electron diffraction patterns give crystallographic information about a material and determine different types of materials which can be amorphous, single crystalline or polycrystalline.. Web the electrons are accelerated in an electron gun to a high potential, such as 5000 v, and are then directed through a thin film of graphite. This includes aspects of how in a general way electrons can act as waves, and diffract and interact with matter. The pattern is a scaled representation of a section of the reciprocal lattice..
