Nationality Germany
Fields Physics

Notable awards Nobel Prize in Physics (1985)

Klaus von Klitzing is a German physicist known for discovery of the integer quantum Hall effect, for which he was awarded the 1985 Nobel Prize in Physics.

In 1962, von Klitzing passed the Abitur at Artland Gymnasium in Quakenbrück, Germany, before studying physics at the Technical University of Braunschweig, where he received his diploma in 1969. He continued his studies at the University of Würzburg, completing his PhD thesis Galvanomagnetic Properties of Tellurium in Strong Magnetic Fields in 1972, and habilitation in 1978. This work was performed at the Clarendon Laboratory in Oxford and the Grenoble High Magnetic Field Laboratory in France, where he continued to work until becoming a professor at the Technical University of Munich in 1980. Von Klitzing has been a director of the Max Planck Institute for Solid State Research in Stuttgart since 1985.

The von Klitzing constant, RK = h/e2 = 25,812.807449(86) Ω, is named in honor of 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. It gives the inverse value of one quantum of electrical conductance.

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