Variation of resistance with time for the NW1 device. Resistance as a function of time for the NW1 device at five temperatures, as indicated. The resistances at 8.0, 4.2, 2.8, and 1.73 K have been offset by 2, 4, 6, and 8 Ω, respectively, for clarity. The arrows indicate four slow fluctuations occurring at ≈ 280, ≈ 370, ≈ 760, and ≈ 945 s in the resistance curve for T = 4.2 K.
