An experimental condensed matter physicist who coauthored the observation of quantized Hall resistance in a two-dimensional electron gas. A silicon transistor supplied the confined carriers; Hall-voltage measurements revealed plateaus insensitive to device geometry. The integer quantum Hall effect therefore connected an electronic transport experiment to precision determination of fundamental constants.[ref]
New Method for High-Accuracy Determination of the Fine-Structure Constant Based on Quantized Hall Resistance by Klaus von Klitzing and others. Byline and abstract: silicon transistor, fixed Hall-resistance values and geometry independence
