Klaus von Klitzing

Klaus von Klitzing (; born 28 June 1943) is a German physicist, known for discovery of the integer quantum Hall effect, for which he was awarded the 1985 Nobel Prize in Physics.

Von Klitzing was born into the old noble Von Klitzing family from the Mittelmark region. He and his family arrived in Lutten near Vechta as German Expellees in 1945. In 1948 they moved to Oldenburg and in 1951 to Essen in the Cloppenburg district.

Education In Essen von Klitzing went to the Protestant elementary School where he was allowed to take advanced classes targeted at older students, and from 1953 onwards he attended the Artland-Gymnasium in Quakenbrück where he earned his Abitur at the top of his class in 1962 .

He then studied physics at the Braunschweig University of Technology, where he received his diploma in 1969. He continued his studies at the University of Würzburg at the chair of Gottfried Landwehr, completing his PhD thesis entitled Galvanomagnetic Properties of Tellurium in Strong Magnetic Fields in 1972, and gaining habilitation in 1978.

Research and career During his career Klitzing has worked at the Clarendon Laboratory at the University of Oxford and the Grenoble High Magnetic Field Laboratory in France (now LNCMI), where he continued to work until becoming a professor at the Technical University of Munich in 1980. He has been a director of the Max Planck Institute for Solid State Research in Stuttgart since 1985.

The von Klitzing constant, RK = h/e2 = is named in honor of Klaus von Klitzing's discovery of the quantum Hall effect, and is listed in the National Institute of Standards and Technology Reference on Constants, Units, and Uncertainty. The inverse of the constant is equal to half the value of the conductance quantum.

More recently, Klitzing's research focuses on the properties of low-dimensional electronic systems, typically in low temperatures and in high magnetic fields.
