A chain of superconductor-insulator-superconductor junctions based on Al-AlO -Al nanostructures and fabricated using conventional lift-off lithography techniques was measured at ultra-low temperatures. At zero magnetic field, the low current bias dynamic resistance can reach values of ≈10 Ω. It was demonstrated that the system can provide a decent quality current biasing circuit, enabling the observation of Coulomb blockade and Bloch oscillations in ultra-narrow Ti nanowires associated with the quantum phase-slip effect.
基于铝-氧化铝-铝纳米结构并采用传统剥离光刻技术制造的超导-绝缘体-超导结链在超低温下进行了测量。在零磁场下，低电流偏置动态电阻可达约10Ω的值。结果表明，该系统能够提供质量不错的电流偏置电路，从而能够观察与量子相位滑移效应相关的超窄钛纳米线中的库仑阻塞和布洛赫振荡。
