Kikuchi line patterns will happen when the material’s thickness is more than expected and almost perfect. Each of these spots represents a set of planes. Secondly, the angles between two vectors are drawn from the centre to two adjacent points. This distance can be considered an average vector to the plane reflection. The first is radius R, which is the difference between the diffracted and the transmitted beams in electron diffraction patterns. There are two parameters in the spot diffraction pattern used to index and interpret such types of electron diffraction. Polycrystalline specimens are pure aluminium or pure gold. So, phases in various polycrystalline materials are determined by interpreting their ring patterns. These patterns are made due to ultrafine grains of polycrystalline materials. The single-crystal material exhibits a spot pattern or Kikuchi line or combination of both Kikuchi and spot pattern, while the PO, crystalline material shows the ring pattern. The formation of each is based on the different conditions of the matter such as crystal structure, thickness, etc. There are three different types of electron diffraction patterns. GED coursework is required for a thorough grasp of structural chemistry.
