...Introduction The date of discovery of the quantum Hall effect (QHE) is known pretty accurately. It occurred in the night between 4th and 5th February, 1980 at 2:00 AM in the morning at the high magnetic lab in Grenoble, France (see Fig. 2.1 ). There is ongoing research on the transport properties...
