Abstract
Higher harmonic generation in mesoscopic metal wires and loops interru pted by tunnel junctions is explored experimentally. When the sample i s biased with a sinusoidal varying current, we observe giant higher ha rmonics in the conductance fluctuations and the Aharonov-Bohm oscillat ions. We demonstrate that the harmonic content is directly related to the probability for an electron to return to the barrier after tunneli ng. The full set of experimental data is in quantitative agreement wit h theoretical predictions. [S0163-1829(98)01915-8].
