![]() | Symko, Orest George | Large steps in long Josephson junctions | Large constant voltage current-steps were observed in the IV-characteristics of long NbN-MgO-NbN Josephson junctions in the presence of external magnetic fields of a few Gauss. The steps are separated by a voltage AV corresponding roughly to 3 to 5 times the voltage spacing expected between adjacent... | NbN-MgO-NbN; Long junctions; Current-steps; Voltage | 1993-03 |

![]() | Symko, Orest George | Tunneling studies of mesoscopic all-NBN junctions | A scanning tunneling microscope (STM) was used to position a NbN tip near a NbN thin film sputtered on a Si substrate. Measurements at 4.2 K clearly show an energy gap of 5.0 mV. The Coulomb blockade of tunneling and the Coulomb staircase, formed by single-electron charging of the central electrod... | All-NbN junctions; NbN | 1993-03 |
