![]() | 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 |
