摘要
We have investigated the response to microwave irradiation of small mesas fabricated on single crystals of Bi2Sr2CaCu2O8+delta. We observe zero-crossing steps in the current-voltage characteristic which are consistent with the intrinsic Josephson junctions in the mesa stack phase-locking to the external microwave field.
