Electron diffraction - Wikipedia
This article provides an overview of electron diffraction and electron diffraction patterns, collective referred to by the generic name electron diffraction. This includes aspects of how in a general way electrons can act as waves, and diffract and interact with matter.

Electron diffraction is a technique that allows determination of the crystal structure of materials. When the electron beam is projected onto a specimen, its crystal lattice acts as a diffraction grating, scattering the electrons in a predictable manner, and resulting in a diffraction pattern.

When a beam of light passes through a row of slits, or is reflected by a row of grooves, it undergoes diffraction and inteference to form a pattern of alternating bright and dark spots – a diffraction pattern.
electron diffraction - Encyclopedia Britannica
Electron diffraction, interference effects owing to the wavelike nature of a beam of electrons when passing near matter. According to the proposal (1924) of the French physicist Louis de Broglie, electrons and other particles have wavelengths that are inversely proportional to their momentum.
Continuous distribution of electrons as a function of angle. If electrons behave as a wave, however, a diffraction pattern will emerge. We can make an analogy with the diffraction of x-rays by a crystal. Crystals act as three-dimensional gratings; they scatter the wave and produce observable interference effects.
11 Electron diffraction and its applications - Oxford Academic
This chapter starts by looking at wave-particle character of electrons. It also explains the Ewald reflecting sphere construction for electron diffraction and provides an analysis of electron diffraction patterns.
Electron Diffraction: Unveiling Atomic Structure, Defects
Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a diffraction pattern that provides information about the arrangement of atoms within the material.
