Fermi conduction level vacant or partially occupied electronic energy level resulting from an array of a large number of atoms in which electrons can freely move 

In 1972 John Bardeen did something that no other physicist, not even Albert Einstein, had ever done. He won his second Nobel Prize in physics. The first was awarded to him (and to Walter H. Brattain and William Shock-ley) in 1956 for investigations on semiconductors and the discovery of the transistor effect.  

Their pioneering efforts ushered in the age of modern electronics and the integrated circuit, which eventually spawned the computer chip and the cell phone. Arguably, the transistor (and all of the devices it has made possible) is the single most important invention of this modern age and ranks with fire for its effects upon society and civilization.

Bardeen, John (1908-1991) received the 1972 Nobel Prize in physics with Cooper and Schrieffer for the BCS theory. It was his second Nobel Prize He won his first in 1956 for his role in the invention of the transistor.

Bardeen, John (1908-1991) A Wisconsin-born electrical engineer and physicist, Bardeen worked for Gulf Oil, researching magnetism and gravity, and later studied mathematics and physics at Princeton University, where he earned a doctoral degree. While working at Bell Laboratories after World War II he, Walter Brattain (1902-1987), and William Shockley (1910-1989) invented the transistor, for which they shared the 1956 Nobel Prize in Physics. In 1972, Bardeen shared a second Nobel Prize in Physics for a jointly developed theory of superconductivity he is the only person to win the same award twice.
