摘要
我们测量了非平稳条件下约瑟夫森结零电压状态下的开关电流分布，通过快速扫偏电流(≌100 kHz)获得，dI/dt高达25 a /s。通过这种方法，我们分析了能级量子化对在能级占据概率远未达到平衡的情况下零电压状态逃逸率的影响。
We have measured the switching current distributions out of the zero-voltage state of Josephson junctions in nonstationary conditions, obtained by means of fast sweeping of the current bias (≌100 kHz) resulting in a dI/dt up to 25 A/s. In this way we have analysed the effects of the levels quantization on the escape rate out of the zero voltage state in conditions where the occupancy probability of the energy levels is far from being in equilibrium.
