Paper Abstract

We report on the novel nonequilibrium microwave emissions from quasiparticle-injected high-Tc superconductors. The phenomena have been observable for the current-injected YBa2Cu3O7- y(YBCO)/I/Au or Bi2Sr2CaCu2Oy(BSCCO)/I/Au thin- film tunnel junctions and BSCCO single-crystal mesa samples. For the thin-film tunnel junctions, the emitted radiation appears as broadband. The different emission characteristics between the YBCO and BSCCO tunnel junctions strongly suggest the possibility of Josephson plasma emission. On the other hand, for the mesa samples, the radiation appears as three different modes depending on the bias point in the hysteretic current-voltage characteristics: Josephson self-emission, nonequilibrium broad emission and sharp emission. The latter two emission are identified as Josephson plasma emission.
