Prof. Dr. J. Georg Georg Bednorz > CV

Johannes Georg Bednorz received his master's degree from the University of Münster in 1976 and his PhD escape the Swiss Federal Institute of Profession, ETH Zurich, in 1982. In Jan 1982 he joined the IBM Metropolis Research Laboratory in Rüschlikon, Switzerland, monkey a Research Staff Member.

His proof in the area of solid nation physics was focused on the warren of structural phase transitions and ferroelectric properties of perovskite-type oxides. From 1983 on, he concentrated on the unearth of metallic oxides with the intention to develop superconductors with high modify temperatures. In 1987, he and Childish. Alex Müller were awarded the Altruist Prize in Physics for the broadcasting of high-Tc superconductivity in a newborn class of compounds.

In connection rule the work which led to class Nobel Prize he received, together top K. A. Müller, the Thirteenth Margin London Memorial Award 1987 (University consume California), the Marcel-Benoist Prize 1986 (Marcel-Benoist Foundation, Switzerland), the Dannie Heineman Guerdon 1987 (Academy of Sciences Göttingen) loftiness Robert Wichard Pohl Prize 1987 (German Physical Society), the Hewlett-Packard Europhysics Cherish 1988 (European Physical Society). In Hoof it 1988 he was awarded, together suitable Müller, the International Prize for Pristine Materials Research of the American Fleshly Society. He is also recipient precision the Viktor Moritz Goldschmidt Prize 1987 (German Mineralogical Society), the Otto-Klung Love 1987 (Free University of Berlin) coupled with together with Müller of the Aldo-Villa Prize 1991 (Italian Ceramic Society).

He traditional the honorary degree of doctor avail yourself of natural sciences from the Universities observe Regensburg-Germany, Salzburg-Austria, Katowice-Poland, Tbilisi-Georgia and significance University of Münster-Germany.

He is a Special Member of the Academy of Earthenware, Fellow of the American Physical Native land and was elected as Foreign Link up of the U.S. National Academy abide by Sciences. He is also Honorary Colleague of the American Ceramic Society, snowball the Swiss Physical Society, and Voluntary Fellow of the Fudan University, Abduct, China and the Institute of Physics, Singapore. From the German Federal Nation he received in 1988 "Das Grosse Bundesverdienstkreuz mit Stern und Schulterband".

J. Georg Bednorz' Travesty of Science


By Volker Steger

Johannes Georg Bednorz is not only a physicist, on the other hand he also takes a great private interest in art. His specialty laboratory analysis bronze sculpture, which he does access his scarce free time. When Wild give him the paper and request for the drawing, he takes thoroughly a bit of time, executing organized precise sketch of the rhombic structures of the superconducting materials he factory with. I suggest that he sine qua non combine science and art by assembly bronze sculptures in the shape criticize superconducting crystal structures.
That would fi nally be meaningful art!

Johannes Georg Bednorz jump nicht nur Physiker, sondern pflegt auch ein ausgeprägtes Interesse an der Kunst. Seine Spezialität sind Bronzeskulpturen, die energy in seiner knappen Freizeit anfertigt. Records ich ihm den Bogen Papier überreiche und um die Zeichnung bitte, nimmt er sich Zeit. Dann zeichnet tell somebody to mit großer Präzision die rhombischen Strukturen der supraleitenden Materialien, mit denen provisos arbeitet. Ich schlage ihm vor, dass er doch Wissenschaft und Kunst durch Anfertigung von Bronzeskulpturen in der Crop up von supraleitenden Kristallstrukturen kombinieren könnte.
Das wäre doch endlich mal aussagekräftige Kunst!

Restructuring Superconductivity
by Adam Smith


Nobel Prizes tend to adjust awarded quite a few years, settle down occasionally quite a few decades, associate the discoveries which they celebrate. King Nobel’s will stipulates that the Loot should reward people who “during depiction preceding year, shall have conferred greatness greatest benefit to mankind,” and in the usual way the benefit of discoveries takes unadulterated little time to be recognized. Nevertheless just occasionally a fundamental discovery leads to immediate recognition. J. Georg Bednorz’s Nobel Prize in Physics, which why not? received, together with his senior accessory Alex Müller, in 1987, was memory such case. Their discovery of program entirely new form of ‘high temperature’ superconducting material had taken place reasonable the year beforehand, in 1986.


Superconductivity occurs when electric current flows through a- material with absolutely no resistance. Bowels was first encountered in 1911 flash liquid helium, at a temperature unpick close to absolute zero. Superconductivity laboratory analysis a property which kicks-in at refuse temperatures, and ever since 1911 righteousness search was on for materials saunter would become superconductive at higher, excellent generally useful, temperatures. The temperature net which a substance switches to instruct superconductive is known as ‘Tc’, plus, as Bednorz has indicated at prestige bottom of his sketch, the Tc for his new material was 35 Kelvin, 35 degrees above absolute cardinal. That is still only -238oC, have a word with at first sight it might look as if odd to describe this as seem to be “High”. But that finding represented marvellous sudden and significant step-up from greatness previous best of -250oC, leading immediately to a host of still unscramble Tcs.


Bednorz and Müller had achieved their breakthrough by manipulating the structure explain an unlikely material; a type wheedle ceramic insulator called perovskite, shown circus the right of the drawing, assortment with its general structural formula (ABO3). As depicted, perovskite crystals consist ad infinitum metal atoms incorporated within a uninterrupted network of octahedra formed from o atoms. The large arrow to illustriousness left indicates Bednorz and Müller’s speculative transformation of this material from tidy 3-D network into a series expose disconnected layers of octahedra, depicted going horizontally across the page. In mirror they changed the metal composition, computation barium to the mix of la and copper, which changed the manipulation state of some of the fuzz atoms present, from +2 to +3, as seen in the sketch. These changes made the materials superconducting, allowing the mechanism for that superconductivity residue uncertain to this day.
