Theodore clusters

from Wikipedia, the free encyclopedia

Theodore Henry Geballe (born January 20, 1920 in San Francisco ) is an American experimental solid-state physicist who deals with superconductivity .

Geballe studied chemistry at the University of California, Berkeley , where he received his bachelor's degree in 1941, and his doctorate in physical chemistry with William Francis Giauque in 1949 . During the Second World War, he did his military service in the US Army in the Pacific for three years. From 1952 to 1970 he was at Bell Laboratories , where he was head of cryogenic physics. In 1968 he became a professor at Stanford University , where he was director of the Centers for Materials Research from 1977 to 1988 and headed the Faculty of Applied Physics from 1975 to 1978. From 1978 he was Theodore and Sydney Rosenberg Professor of Applied Physics . He has been Professor Emeritus since 1990.

Geballe dealt with low temperature physics, where he studied semiconductors, superconductors and magnetic materials. In 1954, together with Bernd Matthias and others , he discovered the niobium-tin superconductor Nb 3 Sn , which (as it was shown in 1961) retains its superconductivity even with high currents and high magnetic fields. It was the first such material to be discovered and was later used, for example, in the coils of fusion reactors ( ITER ). He published over 400 papers.

In 1970 he (with Matthias) received the Oliver E. Buckley Condensed Matter Prize for experiments that challenged theoretical understanding and opened up the field of high-field superconductors . In 1991 he received the Von Hippel Award from the Materials Research Society and in 1989 the first Bernd T. Matthias Prize . He is a member of the National Academy of Sciences (1973), the American Association for the Advancement of Science and the American Academy of Arts and Sciences and a Fellow of the American Physical Society . In 1975 he was a Guggenheim Fellow at the Cavendish Laboratory in Cambridge .

The Theodore H. Geballe Laboratory for Advanced Materials (LAM) in Stanford is named after him.
