Figure 3

(a) Chronological evolution of the current (and voltage) flowing through the nanotube. Point 3 is starred as it indicates the onset of visible shell degradation. (b) Time-resolved resistance variations of the system. A minimum is attained immediately after the Iguest (246 μA), whereas thinning of the CNT leads to increased values of resistance. (c–g) Collection of video frames representative of the core removal progression (forward bias, Au–W electrodes). The process was performed until the total collapse of the carbon shell. The arrow in (c) indicates the contact point of the suspended CNT section to the supporting Au wire. The particles marked with stars in the inset of (c) are in a different image plane from the CNT and never come in contact with it. The plus and minus signs mark the zones in the carbon shell above and below the sublimation temperature of the sulphide core, respectively. All scale bars, 0.5 μm.
