Gerhard Dorda

from Wikipedia, the free encyclopedia

Gerhard Dorda (born May 24, 1932 in Troppau ) is a German physicist and composer.

Dorda is a Sudeten German and grew up in the Czech Republic. At first he wanted to become a musician and studied composition at the Prague Academy of Musical Arts, which he could not finish for political reasons. He then studied physics at Charles University in Prague and, after graduating in 1957, was a research assistant at the Institute for Solid State Physics of the Czechoslovak Academy of Sciences in Prague, where he received his doctorate in 1964. In 1967 he emigrated with his family to the Federal Republic of Germany (initially as a Humboldt fellow at the University of Göttingen) and from 1968 worked as a physicist at Siemens' research laboratories in Munich in semiconductor system development ( MOS silicon semiconductor department ), from 1984 with the rank of director. In 1994 he left Siemens and since then has been a consultant at the University of the Federal Armed Forces in Munich.

In 1971 he demonstrated the surface quantization effects of semiconductors to explain the piezoelectric effect in MOSFETs at room temperature, which he should investigate for their suitability for microphones.

Together with Klaus von Klitzing (then Würzburg) and Michael Pepper he is co-author of the fundamental work on the detection of the quantum Hall effect . The starting point at the time was the investigation of disruptive surface conditions in MOS structures, which Dorda had started to investigate, but for which he initially received no funding from Siemens, as they did not lead to immediately usable products.

After his time at Siemens, he turned to fundamental questions in physics, including quantum effects and the influence of the moon and sun on sensory perception.

In 1986 he received the Wilhelm Exner Medal . He received the Cross of Merit on Ribbon of the Order of Merit of the Federal Republic of Germany.

As a composer, orchestral works, vocal works and chamber music come from him. For this he received the Sudeten German Culture Prize for Music .
