...Von Klitzing's breakthrough, which bears directly on the design of semiconductors, was based on a discovery in 1879 by Edwin Herbert Hall, an American physicist. Hall had observed that electricity traveling through a metallic strip is diverted to one side when a magnetic field is applied perpendicularly to the flow of the current. A measurement of that diverted current is known as Hall voltage. Von Klitzing expected to find that Hall voltage in semiconductors is affected by the material from which they are composed. To his astonishment, Von Klitzing discovered that a measure of the voltage did not depend...
...cornerstone of the quantum theory holds that electrons leap from one energy state to another with mathematical regularity. Von Klitzing provided a practical demonstration of the phenomenon, accurate to within 0.0000001 of a predicted interval. For the past decade, scientists have suspected that Hall voltage conforms to quantum mechanics. "It was not expected, however," noted the Nobel Committee, "that the quantization rule would apply with such high accuracy...
