    Samenvatting

    We analyze the current-voltage characteristics of a Nb superconductor-insulator-superconductor mixer with NbTiN leads to identify the heating processes in this device. We argue that the electron-electron interaction is much faster than the electron-phonon interaction, and show that the heat flow to the bath temperature is limited by the electron-phonon interaction time in the junction. A solution is suggested to considerably reduce the heating. (C) 2000 American Institute of Physics. [S0003-6951(00)03106-5].
