![]() | Symko, Orest George | Multi-fluxon steps in long Josephson junctions and their application to oscillators | Studies of long NbN Josephson junctions of the overlap type in the presence of an external magnetic field show constant voltage steps, of the Fiske type, and large voltage steps. The latter are attributed to multifluxon resonances within the cavity of the junction. The multifluxon steps correspond t... | NbN; Multi-fluxon steps; Oscillators | 1991-03 |

![]() | 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 |
