An experimental <physicist> who coauthored the 1980 report of quantized Hall resistance. A <two-dimensional electron gas> in a silicon transistor exhibited reproducible Hall-resistance values, enabling comparison with fundamental constants. The result showed why the microscopic quality and confinement of a semiconductor device could matter to precision electrical measurement.<New Method for High-Accuracy Determination of the Fine-Structure Constant Based on Quantized Hall Resistance by Klaus von Klitzing and others>[Byline and Hall-voltage measurements in a silicon device]{ref}
