Description
An image is formed in a transmission electron microscope (TEM) by electron diffraction. First observed in 1927 by G.P.Thomson, L.H. Germer, and C.J. Davisson, electron diffraction is used to study the molecular structure of materials. When a directed beam of electrons impinges on a crystalline material, the electrons are diffracted in a geometric pattern (diffraction pattern) that corresponds to the spacings in its structure.
