Nobel Prize-winning Physicist To Give a Talk at BME

Professor Klaus von Klitzing, winner of the 1985 Nobel Prize in Physics, will be a guest at BME on 6 October. The German scientist will give a talk (in English) entitled From the Silicon Transistor to Quantum Metrology: An Unexpected Journey of Basic Research in the Simonyi lecture hall, Building Q, from 14:30 to 15:30.

Von Klitzing was awarded the Nobel Prize for the discovery of the quantized Hall effect. The classical Hall effect, known since 1879, occurs when an electric current flows through a planar electrical conductor in the presence of a magnetic field perpendicular to the plane: a voltage develops between the two sides of the conductor as a result of the Lorentz force acting on the electrons. The quantized Hall effect differs in that, in a sufficiently high-quality two-dimensional electron gas, the Hall resistance changes in discrete steps rather than varying linearly with the magnetic field. Its value can be calculated using a universal constant.

Attendance at the lecture is free, but you must register in advance here.
