What does Clinton J. davisson invented?
Clinton Joseph Davisson, an American physicist, was in the employ of Western Electric (Bell Laboratories), Davisson was mainly involved in thermionics and emission of electrons from metals under electron bombardment. In 1927 Davisson with the aid of L.H. Germer tested and confirmed that if you direct a beam of electrons on to a crystal of nickel, instead of bouncing off, the beam diffracted. For his confirmation of electron waves, Davisson shared the Nobel Prize in physics in 1937 with G.P. Thomson.
