| Outline of Final Research Achievements |
We fabricate normal-metal/insulator/superconductor tunnel junction for the developments of the solid state refrigerator. The effect of cooling is evaluated by comparing the conductance spectra of the N/I/S junction with theoretical curve. We find that the temperature of the junction is 0.27K when the bath temperature is 0.5K, indicating a successful operation of the present device. In cases of the ferromagnet(F)/I/S junction, since enough junction quality is not obtained so far, we are retuning the process of the junction fabrication.
