The Davisson–Germer experiment was conducted from 1923 to 1927 by Clinton Davisson and Lester Germer at Western Electric. Electrons, scattered by the surface of a crystal of nickel metal, displayed a

Graph of the electrical current vs electron beam azimuth angle from the 1927 "The Scattering of Electrons by a Single Crystal of Nickel" paper. The presence of peaks and troughs is consistent with a diffraction pattern and suggests a wave-like nature of electrons.

Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave-like behavior. For e
