A Nobel Prize-winning physicist who pioneered the field of superconductivity, making groundbreaking discoveries that transformed our understanding of materials and their properties.
Ivar Giaever is a Norwegian-American engineer and physicist who shared the Nobel Prize in Physics in 1973 with Leo Esaki and Brian Josephson for their pioneering discoveries regarding tunneling phenomena in solids. Giaever's groundbreaking work, which demonstrated the existence of an energy gap in superconductors, earned him international recognition and cemented his position as a leading authority in the field of superconductivity.
Giaever was born on April 5, 1929, in Norway. He earned a degree in mechanical engineering from the Norwegian Institute of Technology in Trondheim in 1952. After emigrating to Canada in 1954, Giaever worked for the Canadian division of General Electric before moving to the United States in 1958. He joined General Electric's Corporate Research and Development Center in Schenectady, New York, and later earned a Ph.D. degree from the Rensselaer Polytechnic Institute in 1964.
Giaever's Nobel Prize-winning work was performed at General Electric in 1960. Building on Esaki's discovery of electron tunneling in semiconductors in 1958, Giaever demonstrated that tunneling also took place in superconductors. His experiments showed that tunneling could occur through a very thin layer of oxide surrounded by metal in a superconducting or normal state. This discovery provided strong evidence for the existence of an energy gap in superconductors, a key prediction of the BCS theory of superconductivity.
Giaever's work on superconductivity led to numerous breakthroughs and innovations. Some of his notable contributions include:
