Figure 4

a Linear conductance of a metallic DWCNT (sample No. 2) as a function of time, recorded under periodicVGpulse at different temperature (curves shifted for clarity), which shows that the DWCNT exhibits electrical hysteresis behavior at high temperature (>72.39 K) and is electrically unstable at low temperature (<72.39 K).b ThedI/dV curves of the DWCNT recorded repeatedly after being disturbed by a positiveVGpulse (15 V) at 2.280 K in another thermal cycle
