The quantum Hall effect was discovered in 1980 by Klaus von Klitzing at the Max Planck Institute for Solid State Research. It occurs when electrons move through extremely thin semiconductor layers at very low temperatures and under strong magnetic fields. Under these conditions, an astonishing phenomenon emerges: electrical resistance does not change continuously, but in precise, quantized steps—always a multiple of a fundamental constant. This quantization is so exact that it now serves as the basis for defining the electrical unit ohm. The discovery was not only a breakthrough in fundamental physics but also revolutionized precision measurement—earning the Nobel Prize in Physics in 1985.
