Zero Resistance

The microwave-excited high mobility two-dimensional electron system exhibits, at liquid helium temperatures, vanishing resistance in the vicinity of B=[4/(4j+1)]Bf, where Bf=2πfm*/e, m* is an effective mass, e is the charge, and f is the microwave frequency. Here, we summarize some experimental results.
