Lothar Nordheim

Lothar Wolfgang Nordheim (November 7, 1899 – October 5, 1985) was a German–American theoretical physicist. He was a pioneer in the applications of quantum mechanics to solid-state problems, such as thermionic emission, work function of metals, field electron emission, rectification in metal-semiconductor contacts and electrical resistance in metals and alloys. He also worked in the mathematical foundations of quantum mechanics, cosmic rays and in nuclear physics.
