Günter Albrecht (2002)

Günter Albrecht (born February 14, 1930 in Greußen , Sondershausen district ; † October 19, 2015 in Jena ) was a German experimental physicist who deals with solid-state physics , low-temperature physics and superconductivity .

Life

From 1957 Günter Albrecht worked at the Physics Institute of the University of Jena under the direction of Professor Wilhelm Schütz, where in 1962 he wrote his dissertation on X-ray structure analysis to elucidate chemical bonds. In 1967 he submitted his habilitation thesis on the electronic structure of organometallic complex compounds and transition metal hydrides. In 1968 he became a lecturer and was full professor for applied physics from 1969 to 1978. He built up the department (from 1973 as a scientific area) "Detector Physics" (today the Working Group on Low Temperature Physics at the Institute for Solid State Physics of the Physics and Astronomy Faculty of the University of Jena ). His work onLow-temperature physics / solid-state physics focused on super-sensitive measuring methods based on superconductivity (superconducting bolometer , SQUID ) through to applications in biomagnetism (first magnetocardiogram in 1978) and on the Josephson voltage standard for representing the SI unit volt . 1970–73 he was director of the physics section at FSU Jena and in 1974 received the National Prize III. Class for science and technology together with Franz Klapper, Hans-Joachim Köhler, Joseph Müller and Wolfgang Richter for "researching superconducting layer processes, their microstructuring and their application in measurement technology". In 1978 he became a corresponding and in 1981 a full member of the Academy of Sciences of the GDR and in 1979 was appointed head of the research area Physics, Nuclear and Materials Sciences at the Academy of Sciences of the GDR (AdW) Berlin to coordinate the “complex research tasks” on microelectronics , fiber optics -Communication, laser technologies and high temperature superconductivity . From 1982 to 1984 he was also the founding director of the Physikalisch-Technische Institut (PTI) of the AdW in Jena (today the Institute for Photonic Technologies ). From 1988–91 he was secretary of the Technical Sciences class of the AdW and its vice-president. He has been retired since 1993, but continued to advise public institutions and private companies on scientific issues, such as theoretical questions about isotope-pure materials in microelectronics. He was a member of the Leibniz Society. V. Berlin . In 1986 the Technical University of Karl-Marx-Stadt awarded him an honorary doctorate.

Günter Albrecht had been married for the first time since 1954 and had two children.
