Modeling the power flow in normal conductor-insulator-superconductor junctions
Normal conductor-insulator-superconductor ~NIS! junctions promise to be interesting for x-ray and phonon sensing applications, in particular due to the expected self-cooling of the N electrode by the tunneling current. Such cooling would enable the operation of the active element of the sensor below the cryostat temperature and at a correspondingly higher sensitivity. It would also allow the us...
متن کاملSpin current in ferromagnet / insulator / superconductor junctions
A theory of spin polarized tunneling spectroscopy based on a scattering theory is given for tunneling junctions between ferromagnets and d-wave superconductors. The spin filtering effect of an exchange field in the insulator is also treated. We clarify that the properties of the Andreev reflection are largely modified due to a presence of an exchange field in the ferromagnets, and consequently ...
متن کاملInsulator interface effects in sputter . . deposited NbN / MgO / NbN ( superconductor - insulator - superconductor } tunnel junctions
All refractory, NbN/MgO/NbN (superconductor-insulator-superconductor) tunnel junctions have been fabricated by in situ sputter deposition. The influence ofMgO thickness (0.8-6.0 nm) deposited under different sputtering ambients at various deposition rates on current-voltage (IV) characteristics of small-area ( 30 X 30 pm) tunnel junctions is studied. The NbN/MgO/NbN trilayer is deposited in sit...
متن کاملResponse time of a thermometer based on normal metal–insulator–superconductor (NIS) tunnel junctions
We have measured the thermal response of a superconductor–normal metal–superconductor (SINIS) tunnel junction structure at substrate temperature ∼ 60 mK by directly heating the electron system in the normal metal island. In our structure, we /nd the response time is determined by the electron–phonon coupling in the electron temperature range 300–600 mK. By using AC heating, the cut-o4 frequency...
متن کاملPeltier refrigeration by a pair of normal metal / insulator / superconductor junctions
We suggest and demonstrate in experiment that two normal metal /insulator/ superconductor (NIS) tunnel junctions combined in series to form a symmetric SINIS structure can operate as an efficient Peltier refrigerator. Specifically, it is shown that the SINIS structure with normal-state junction resistances 1.0 and 1.1 kΩ is capable of reaching a temperature of about 100 mK starting from 300 mK....
