ⓘ Georg Bednorz

Johannes Georg Bednorz is a German physicist who, together with K. Alex Muller, discovered high-temperature superconductivity in ceramics, for which they shared the 1987 Nobel Prize in Physics.

                                     

1. Life and work

Bednorz was born in Neuenkirchen, North Rhine-Westphalia, Germany to elementary-school teacher Anton and piano teacher Elisabeth Bednorz, as the youngest of four children. His parents were both from Silesia in Central Europe, but were forced to move westwards in turbulences of World War II.

As a child, his parents tried to get him interested in classical music, but he was more practically inclined, preferring to work on motorcycles and cars. Although as a teenager he did eventually learn to play the violin and trumpet. In high school he developed an interest in the natural sciences, focusing on chemistry, which he could learn in a hands-on manner through experiments.

In 1968, Bednorz enrolled at the University of Munster to study chemistry. However, he soon felt lost in the large body of students, and optrf to switch to the much less popular subject of crystallography, a subfield of mineralogy at the interface of chemistry and physics. In 1972, his teachers Wolfgang Hoffmann and Horst Bohm arranged for him to spend the summer at the IBM Zurich Research Laboratory as a visiting student. The experience here would shape his further career: not only did he meet his later collaborator K. Alex Muller, the head of the physics department, but he also experienced the atmosphere of creativity and freedom cultivated at the IBM lab, which he credits as a strong influence on his way of conducting science.

After another visit in 1973, he came to Zurich in 1974 for six months to do the experimental part of his diploma work. Here he grew crystals of SrTiO 3, a ceramic material belonging to the family of perovskites. Muller, himself interested in perovskites, urged him to continue his research, and after obtaining his masters degree from Munster in 1977 Bednorz started a PhD at the ETH Zurich Swiss Federal Institute of Technology under supervision of Heini Granicher and Alex Muller. In 1978, his future wife, Mechthild Wennemer, whom he had met in Munster, followed him to Zurich to start her own PhD.

In 1982, after obtaining his PhD, he joined the IBM lab. There, he joined Mullers ongoing research on superconductivity. In 1983, Bednorz and Muller began a systematic study of the electrical properties of ceramics formed from transition metal oxides, and in 1986 they succeeded in inducing superconductivity in a lanthanum barium copper oxide LaBaCuO, also known as LBCO. The oxides critical temperature T c was 35 K, a full 12 K higher than the previous record. This discovery stimulated a great deal of additional research in high-temperature superconductivity on cuprate materials with structures similar to LBCO, soon leading to the discovery of compounds such as BSCCO T c 107K and YBCO T c 92K.

In 1987, Bednorz and Muller were jointly awarded the Nobel Prize in Physics "for their important break-through in the discovery of superconductivity in ceramic materials". In the same year Bednorz was appointed an IBM Fellow.
