Frankfurt am Main Frankfurt am Main () is the most populous city in the States of Germany, German state of Hesse. Its 773,068 inhabitants as of 2022 make it the List of cities in Germany by population, fifth-most populous city in Germany. Located in the forela ...

in 1967, he enrolled in architectural engineering at the TH Darmstadt, but later moved to the
Goethe University Frankfurt Goethe University Frankfurt () is a public research university located in Frankfurt am Main, Germany. It was founded in 1914 as a citizens' university, which means it was founded and funded by the wealthy and active liberal citizenry of Frankfurt ...
to study physics, but since he had missed the registration period for physics, he began with a mathematics and later changed to physics, qualifying for his Diploma in the laboratory of Werner Martienssen. Here he was supervised by Eckhardt Hoenig, and worked alongside another future Nobel laureate, Gerd Binnig. Störmer moved to France to carry out his PhD research in Grenoble, working in a high-magnetic field laboratory which was run jointly between the French CNRS and the German Max Planck Institute for Solid State Research. Störmer's academic advisor was Hans-Joachim Queisser, and he was awarded a PhD by the University of Stuttgart in 1977 for his thesis on investigations of electron hole droplets subject to high magnetic fields. He also met his wife, Dominique Parchet, while working in Grenoble. They divorced each other a few years later. After receiving his PhD, Störmer moved to the US to work at

Research career

Perhaps as important as the work for which he won the Nobel prize is his invention of modulation doping, a method for making extremely high mobility two dimensional electron systems in semiconductors. This enabled the later observation of the fractional quantum Hall effect, which was discovered by Störmer and Tsui in October 1981 in an experiment carried out in the Francis Bitter High Magnetic Field Lab at the
Massachusetts Institute of Technology The Massachusetts Institute of Technology (MIT) is a Private university, private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of moder ...
. Within a year of the experimental discovery, Robert Laughlin was able to explain its results. Störmer, Tsui and Laughlin were jointly awarded the 1998 Nobel Prize in Physics for their work.Nobel Prize press release
