Summary of scientific research
Prof. Klitzing was awarded the Nobel Prize for Physics in 1985 for his discovery of the quantized Hall resistance. Prof. Klitzing demonstrated that electrical resistance occurs in very precise units by using the Hall effect in two-dimensional conductors. The Hall effect denotes the voltage that develops between the edges of a current-carrying ribbon placed between the poles of a magnet. The ratio of this voltage to the current is called the Hall resistance. When the magnetic field is very strong and the temperature very low, the Hall resistance varies in discrete jumps, first observed by Klitzing. The value of the fundamental quantized resistance is extremely precise, internationally known as von Klitzing constant. The significance of Klitzing's discovery, made in 1980, was immediately recognized and triggered the introduction of a new international system of units based on constants of nature. The quantum Hall effect has connections to nearly all areas in physics, starting from quarks in high energy physics to black holes in astrophysics and is regarded as the first topological insulator. In general, von Klitzing's research includes optical and transport measurements on semiconductor quantum structures.
